How can a car moving with a velocity of 10 Metre per second be stopped?

How can a car moving with a velocity of 10 Metre per second be stopped?

A car moving with velocity of 10m/sec can be stopped by application of a constant force F in a distance of 20m.

What is the acceleration of the velocity changes from 45m s to 60m s in three seconds?

Answer. Answer: Acceleration = change of velocity/ time so 60-45/3 so 15/3=5.

What is the velocity of the car at the end of 10 seconds?

Explanation: the car was initially at rest so the initial velocity is 0. Thus,the position of car at the end of 10s is 400m far from its initial position. Thus the velocity of the car at the end of 10s is 80m/s 80 m/s.

How much force is required to stop a bus in 10 seconds of mass?

Expert-Verified Answer Force used to stop the bus = mass of the bus in kg× deceleration = 5000 kg× – 2 m/s² = – 10,000 N. The minus sign implies force is supplied by the decelerating agency.

When a car stops what is its velocity?

We know the final velocity is zero because the car has stopped. The only unknown in this equation is the acceleration a. The car decelerates (accelerating in the opposite direction of its motion) because there is an unbalanced force on it.

What is the formula for acceleration to speed?

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). Acceleration is also a vector quantity, so it includes both magnitude and direction. Created by Sal Khan.

What is the formula for displacement?

S = ut + ½ at2 Hence, displacement (s) of an object is equal to initial velocity(u) times time (t), plus half of the acceleration (½ a) multiplied by time squared (t2).

What is the formula for velocity using acceleration?

Velocity = acceleration × time.

What is the acceleration of the object at T 2.5 s?

Answer and Explanation: The gradient in the interval with t= 2.5s is constant and thus the velocity is constant. From the definition of acceleration i.e., it is the rate of change of velocity, there is no change in the velocity and this the acceleration is zero.

What is the velocity of the body after 10 seconds and 40 seconds?

n after 40 sec.? The velocity of the body is 20 m/s after 10 seconds and 0 m/s after 40 seconds.

What is the final velocity of a car that accelerates a 10 m s2 from rest and traveled 180 m?

What is the final velocity of a car that accelerated 10 m/s2 from rest and traveled 180m? V2=u2+2ad=zero2+2*10*180, v2=3600, so v=60 m/s.

What do you mean by acceleration of a moving vehicle is 10 Metre per second?

Explanation: Acceleration is the rate of change of velocity of a body w.r.t time. Thus, if the acceleration of a body is 10m/s^2 , it means that the body accelerates after every second with a velocity of 10m/s.

Can we stop a fast moving car instantaneously explain?

No, we cannot instantaneously stop a fast moving automobile as it requires sudden change in momentum which is not possible. Changing momentum is a gradual process as it requires force to act over a period of time.

⇒⇒ u = 25 m/s.

How does velocity affect stopping distance?

Braking distance depends on how fast a vehicle is travelling before the brakes are applied, and is proportional to the square of the initial speed. This means that even small increases in speed mean significantly longer braking distances.
