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

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 would be the net force on the car if it were moving to the left?

A)If a car is moving to the left with constant velocity then the net force applied to the car is zero. B) An object cannot remain at rest unless the net force acting on it is zero.

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

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

## 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 does Newton’s 2nd law state?

Newton’s second law of motion states that F = ma, or net force is equal to mass times acceleration. A larger net force acting on an object causes a larger acceleration, and objects with larger mass require more force to accelerate.

## What is Newton’s second law of speed?

His second law defines a force to be equal to change in momentum (mass times velocity) per change in time. Momentum is defined to be the mass m of an object times its velocity V.

## How do you find the net force of a car?

- F is the net force.
- m is the mass of the object.
- a is acceleration.

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

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

## Is momentum calculated with KG?

In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.

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

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

## How much work is done to move a 1400 kg car?

Hence, the work done against the friction =20300 J. A car weighing 1400 kg is moving at a speed of 54 km/h up a hill when the motor stops. If it is just able to reach the destination which is at a height of 10 m above the point, calculate the work done against friction (negative of the work done by the friction).

## 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).

## 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 .

## What is a 1000 kg car traveling with a velocity of 20 meters per second east experiences?

A 1000. -kilogram car traveling 20.0 meters per second east experiences an impulse of 2000.

## 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.

## 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 kinetic energy of a 1000 kg roller coaster car that is moving with a speed?

Expert-Verified Answer The kinetic energy of the roller coaster at the given mass and speed is 200,000 J. The given parameters; mass of the roller coaster, m = 1000 kg. speed of the roller coaster, v = 20 m/s.
