## What does a 1000 kg car traveling 20 meters per second east experience?

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

## What is the speed of a 1.0 x10 3 kilogram car?

A 1.0 × 10³-kilogram car travels at a constant speed of 20 meters per second around a horizontal circular track.

## Which situation will produce the greatest change in momentum?

The momentum change is dependent upon the velocity change; the object with the greatest velocity change has the greatest momentum change.

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

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

## 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.

## What is the acceleration of a car with a mass of 1 200 kg?

In this case, the mass of the car and the force exerted on it are provided as information. Therefore, the acceleration of the car is 0.5 m s−2 when its engine exerts a force of 600 N .

## 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 SI unit of force?

The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.

## What is the SI unit of momentum?

Momentum
SI unit kilogram meter per second (kg⋅m/s)
Common symbols p, p
Other units slug⋅ft/s

## Is momentum is a vector?

The momentum of a body is a vector quantity, for it is the product of mass, a scalar, by velocity, a vector.

## 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 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).

## What is the rate in kilometers per hour when a car travels 20 meters per second?

Convert m/sec to km/hr we multiply the given number by 18/5. ∴ Its speed in km/hr is 72.

## When a car travels 20 km in 20 minutes?

Expert-Verified Answer So if car travel need to travel 20 km in 20 min i.e 1/3 hr so it must be move with speed 60 km/hr.
