## 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.

## 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 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 momentum of 1000 kg car moving northward at 20 m?

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

## 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 much work is required to stop a car of 1000 kg moving with speed of 72 km h?

Expert-Verified Answer Work required to stop a car is 400000 Joule or 400 kilojoule.

## What happens when a mass of 20 kg moving with a speed of 10 Metre per second collides with another stationary?

A mass of 20 k g moving with a speed of 10 m s – 1 collides with another stationary mass of 5 k g . As a result of the collision, the two masses stick together.

## What is the speed of a moving car is 20 m per second?

⇒72 km h−1.

## 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.

## Does velocity mean speed?

Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.

## 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.

## 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 the momentum of a 1500 kg car?

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

## What is the momentum of a 20 kg body moving with a velocity of 10 m per second?

Hence the momentum of the body is 200 kg. m/s.

## What is the linear momentum of a car of mass 1000kg?

Momentum of the car is : P = m×v =1000×10=10000kgm/sec.

## How much force is needed to accelerate 1000 kg car at a rate of 3m s?

hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N .

## How much force is needed to accelerate a 1000 kg?

Hence, the force needed to accelerate the 1000 kg car by 3ms2 is 3000 N.

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

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

## What is the minimum work needed to push a 1000 kg car 300 m up a 17.5 incline?

In summary, the minimum work needed to push a 1000kg car 300m up a 17.5o incline, ignoring friction, is 2803927Joules.
