What will be the momentum of a car having mass of 1000 kg is moving with a velocity of 0.5 m s?

We know that Momentum p = Mass m × Velocity v Therefore p = 1000 kg × 0.5 m/s = 500 kg m/s Thus momentum of the car = 500 kg m/s.

How much force is required by a car of mass 1000 kg starting from rest to gain a velocity of 30 metre per second in 10 second?

Thus, force required is 4500 N. Q. Calculate the force required to accelerate a car from rest to a velocity of 30 ms−1 in 10 seconds.

When a car travels in a circular path with constant speed?

The car goes around and around at constant angular velocity.In summary, for a car traveling in a circular path with constant speed, the only quantity that is constant and non-zero is angular velocity, as both the magnitude of linear velocity and the distance from the axis of rotation to the particle remain constant.

How to calculate acceleration?

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).

What is the formula for constant acceleration?

How do you find constant acceleration? One can use the acceleration formula to find the rate of change in velocity between two moments. It is calculated by a = (V-Vo)/t, where a is acceleration, V and Vo are final and initial velocities, and t is time.

What is the momentum of a 1200 kg car with a velocity of 25 m s?

Answer and Explanation: We can find the momentum of the car by multiplying the mass times the velocity. Because both the mass and velocity are given in SI units, we do not need to perform any unit conversion before multiplying. Hence, we have shown that the momentum of the car is 30000 kg m/s.

What is the momentum of 1000 kg car moving northward at 20 m?

p = mv = (1000kg)(20m/s) = 20000 kg m/s, northward • c.

What is the momentum of a 1500 kg car?

Therefore p=1500*20 = 30,000 kg m/s.

What is the SI unit of force?

The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.

What is the force required to stop a car of mass 1000 kg?

FORCE (F) = ? OR , a = 2.5 m/s2. = 2500 N.

What is the force required to move a body of mass 1000 kg?

Answer: The force required to move a body of mass 1000kg is 4000 N. The force required to move a body is F = μmg, where μ is the coefficient of friction, m is the mass of the body and g is gravity. hence, the force required to move 1000 kg if the coefficient of friction is 0.4 will be 4000N.

What is the motion of a car on a circular path?

Car moving on circle path it is called circular motion. This type of motion associated with the given example. Circular motion means the object moving on the circumferences of a circle or rotation along with a circular path. In this example, the car was moving on the circular path so it called circular motion.

Why is a car moving around a circular path accelerating?

Acceleration is a change in velocity, either in its magnitude—i.e., speed—or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant.

What is an object moving in a circle with constant speed called?

Therefore, the object moving in a circle at a constant speed is accelerating toward the center of the circle. The acceleration toward the center of the circle is called centripetal acceleration.

What is the acceleration on a car that is moving at a constant velocity?

Correct answer: If an object is moving with constant velocity, then its acceleration must be zero. We can then look at Newton’s second law. If the acceleration is zero, then the net force must also be zero.

What is the acceleration of a motor car travelling at 30 metre per second on a circular road of radius 500 m?

ac=v2rac=30×30500=95=1.8m/s2at=2m/s2anet=√(1.8)2+(2)2=√7.24=2.7m/s2.

What is the acceleration of a car that speeds up from 12m s to 30m s in 15 seconds?

the acceleration of a car with speeds up from 12 metre per second to 30 metre per second in 15 second is equal to 1.2 metre per second square. Explanation: The rate of change of linear velocity is defined as the acceleration.

What is the acceleration of a car that is moving at a constant speed in a straight line?

Explanation: Acceleration is defined as the rate of change of velocity. In the given problem the car travels in a straight line at a constant speed. Or there is zero acceleration of the car.
