# What is a 500 kg car moving with velocity 36 km per hour on a straight road unidirectionally?

## What is a car of mass 500 kg moving with speed 36 km per hour?

Power=500×30×102×60=1250W.

## What is the centripetal force of a 500 kg car moving with a velocity of 36 km hr?

m=500 kg, r=50mv=36 kmph=36×518=10ms−1F=mv2r=500×10×1050=1000N.

## What is the kinetic energy of a car of mass 500 kg moving with a velocity?

Velocity of car, v = 36 km/hr = 36 × (5/18) = 10 m/s. Mass of car , m = 500 kg. Kinetic energy = (1/2) m v2 = (1/2) × 500 × 10 × 10 = 25000 J = 25 kJ.

## What is the speed of 500 kg car that has a kinetic energy of 64 kJ?

Kinetic Energy (KE) = 64 kJ = 64 × 103 J. ∴ Speed of the car = 16 m/s.

## 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 a car of mass 1000 kg moving with a velocity of 45km h?

A car of mass 1000 kg moving with a velocity of 45 km/h collides with a tree and comes to stop in 5 s. The force exerted by car is 2500 N. Force = mass × retardation ⇒F=1000 × (2. 5) ⇒F=2500 N The force exerted by the car on the tree is 2500 N.

## How much speed does a truck of mass 1000 kg change from 36 km per hour to 72 km per hour in 2 minutes?

Power =Work doneTime=1.5×105120=1250 W. Q. A truck weighing 1000kgf changes its speed from 36km h−1 to 72km h−1 in 2 minutes. (g=10ms−2).

## 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 formula for centripetal speed?

For a mass M with tangential speed v at radius R, the centripetal force is Fc = Mv2/R. With a period of T, the linear speed is v = 2πR/T and the centripetal force is Fc = 4π2MR/T2. You will change Fc, mass, and radius to measure the effect on the period of rotation. 1.

## Is centripetal force equal to velocity?

Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the Fc, the smaller the radius of curvature r and the sharper the curve. The second curve has the same v, but a larger Fc produces a smaller r′.

## What is the formula for centripetal force and velocity?

Centripetal force = mass x velocity2 / radius.

## When the speed of a car weighing 1500 kg increases from 36 km per hour to 72 km per hour uniformly?

The change in momentum of a car weighing 1500 kg when its speed increases from 36 km/h to 72 km/h = 30000 kg. m/s − 15000 kg. m/s = 15000 kg. m/s.

## What is a car moving with a speed of 36 km per hour in 15 minutes?

Hence, the distance traveled by the car in 15 minutes is 9 km.
