A 500 kg car was initially at rest travelled with an acceleration of 5ms\(^{-2}\), what is it's kinetic energy after 4s?

What is the acceleration due to gravity 'g' on the moon, if g is 10 ms\(^{-2}\) on the earth?

A uniform rod PQ of mass 2kg and length of 1m is pivoted at the end P. if a load of 14N is placed on it at the centre, find the force that should be applied vertically upwards at Q to maintain the rod in equilibrium hori…

A body is projected from the earth's surface with the hope of letting it escape from the earth's gravitational field. What is the minimum escape velocity? [Earth's radius = 6.4 \(\times\) 10\(^3\) km, g = 10 ms\(^{-2}\)]

A vehicle of mass m is driven by an engine of power P from rest. Find the minimum time it will take to acquire a speed v.

A quantity of ice at -10\(^{\circ}\)C is heated until the temperature of the heating vessel is 90\(^{\circ}\)C. Which of the following constants is NOT required to determine the quantity of heat supplied to the vessel?

An electric kettle with negligible heat capacity is rated at 2000 W. If 2.0 kg of water is put in it, how long will take temperature of water to rise from 200 to 1000? [Specific heat capacity of water = 4200 J Kg\(^{-1}\…

The ice and steam points of a thermometer are 20mm and 100mm respectively. A temperature of 750C corresponds to Y mm on the thermometer. What is Y?
