## Is a 1000 kg vehicle moving with a speed of 20 m per second is brought to rest in a distance of 50 m?

A 1000 kg vehicle moving with a speed of 20m/s is brought to rest in a distance of 50 meters : (i) Find the acceleration. (ii)Calculate the unbalanced force acting on the vehicle. Hence, the unbalanced force acting on the vehicle is -4000N.

## What is the average braking force of a 1000 kg car?

Answer: The average braking force is 2000 N.

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

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.

## What is the mass 1000 kg with velocity 10 meters per second?

P = m×v =1000×10=10000kgm/sec. Was this answer helpful?

## How much work is required to accelerate a 1000 kg car from 20m * S 1 to 30m S 1?

The work required to accelerate a 1000 kg car from 20 m/s to 30 m/s is equal to 250,000 joules.

## What is the average braking force of a 1000 kg car moving at 20m s?

Therefore, the force applied by the brakes is 2000 N. Q. A car of mass 1000 kg moving with a velocity of 20 m/s is brought to rest by applying brakes in 10 seconds.

## How to calculate velocity?

Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

## What is braking force formula?

Kinetic energy is given by E = (1/2)mv^2 and Work is W = FS ; hence E = FS thus (1/2)mv^2 = FS ; Thus F = (1/2)mv^2/S. For the given values F = 0.5x 800 x 8.9^2/S = 31684/S. You have to give a value of the breaking distance to be able to find the force needed to stop the car.

## How much net force is required to accelerate a 1000 kg?

So the net force is required to accelerate a 1000 kg car at 4.00 m/s2 is 4000 N.

## What is the momentum of a 1500 kg car?

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

## What is the momentum of a 1000 kg object that is not moving?

The momentum of any object that is at rest is 0.

## 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 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).
