A car is being driven by a force of `2.5 xx 10^(10)` N. Travelling at a constant speed of 5 m/s, it takes 2 minutes to reach a certain place. Calculate the work done.

A man carries a suitcase on head by applying a force of 20 N . He travels a horizontal a distance of 10 m and then climbs a vertical distance of 5 m . Calculate the total work done by him .

A car travels with a speed of 25 m//s for 2 minutes and then with 20 m//s for 1 minute.Calculate the total distance travelled by the car.

The speed v reached by a car of mass m in travelling a distance x, driven with constant power P, is given by

The speed v reached by a car of mass m in travelling a distance x, driven with constant power P, is given by

A car travels with a speed of 25 m//s for 2 minutes and then with 20 m//s for 1 minute.Define average speed.

A women weighing 600 N is sitting in a car which is travelling at a constant speed on a straight road. The car suddenly goes over a humb in the road (humb may be regarded as an arc of a circle of radius 12.1m) . If the women experiences weightlessness, calculate the speed of the car. [Take g=10 m//s^2 ]
