What is the kinetic energy of a car of mass 500kg moving with a velocity of 36km h?

What is the kinetic energy of a car of mass 500kg moving with a velocity of 36km h?

Velocity of car, v = 36 km/hr = 36 × (5/18) = 10 m/s. Mass of car , m = 500 kg. Kinetic energy = (1/2) m v2 = (1/2) × 500 × 10 × 10 = 25000 J = 25 kJ. KInetic energy is proportional to square of velocity .

What is the centripetal force of a 500 kg car moving with a velocity of 36 km hr?

m=500 kg, r=50mv=36 kmph=36×518=10ms−1F=mv2r=500×10×1050=1000N.

What is a 500 kg car moving with velocity 36 km per hour on a straight road unidirectionally?

Hence, the answer is 1250W. Was this answer helpful?

What net force is required to keep a 500 kg object moving with a constant velocity of 10m s?

Correct answer: A net force is only required to change an object’s motion. The 500 kg object is moving at a constant velocity; therefore, there is no net force (0 Newtons) acting on the object.

What is the kinetic energy of a 1500 kg car moving at 20 ms?

Therefore, the kinetic energy of the car is 300,000 J.

What is the kinetic energy of a car of mass 1000 kg moving at 20 ms 1?

By using the equation: Kinetic Energy = (1/2)mv^2, using m as 1000kg and v as 20ms^-1. We can calculate this value as follows: KE = (1/2)(1000)(20)^2This is equal to 2.0*10^5J (solved using a scientific calculator).

What is the centripetal force acting on a car of mass 500 kg?

∴ Centripetal force F=mv2R=500×10250=1000N.

What is the formula for centripetal speed?

For a mass M with tangential speed v at radius R, the centripetal force is Fc = Mv2/R. With a period of T, the linear speed is v = 2πR/T and the centripetal force is Fc = 4π2MR/T2. You will change Fc, mass, and radius to measure the effect on the period of rotation. 1.

Is centripetal force equal to velocity?

Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the Fc, the smaller the radius of curvature r and the sharper the curve. The second curve has the same v, but a larger Fc produces a smaller r′.

What is the speed of 500 kg car that has a kinetic energy of 64 kJ?

Kinetic Energy (KE) = 64 kJ = 64 × 103 J. ∴ Speed of the car = 16 m/s.

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.

How do you calculate the speed of a moving vehicle?

The formula for speed and distance is the same for a car as any other object: distance ÷ time. So if you want to calculate the speed of a car at sixty miles an hour, the math is (60 x 5280) ÷ (60 x 60) = 88 feet per second.

What is the kinetic energy of a car of mass 500kg is moving with a speed of 60m s?

Ans) The kinetic energy of the car is 900000 J which is equal to 900 kJ.

What is a car of mass 1000 kg moving with a velocity of 45km h?

A car of mass 1000 kg moving with a velocity of 45 km/h collides with a tree and comes to stop in 5 s. The force exerted by car is 2500 N. Force = mass × retardation ⇒F=1000 × (2. 5) ⇒F=2500 N The force exerted by the car on the tree is 2500 N.

What is the kinetic energy of a car of mass m moving with velocity v?

Expression for the kinetic energy If a body of mass m is moving with a speed v, its kinetic energy is given as K.E. = mv2.
