What is the work that must be done to stop a lorry of mass 4000kg moving at a velocity of 54km/hr in 2 seconds? 2. A body of mass 20 kg is moving with a constant velocity of 100m/s at a height 200m above the ground. Calculate its total energy. 3.A body of mass 200kg is projected vertically upwards with a velocity of 300m/s. Assuming that all its kinetic energy is converted into potential energy, Calculate the maximum height reached by it. 4.A crane with a 10kW engine lifts a load at a constant velocity of 60m/min. What is the mass of the load? Assume 100% efficiency for the crane’s engine. 5.A car of mass 3 * 103 kg travelling at 36 km/hr is brought to rest at a distance of 100m. Calculate the power required to do so. 6.A cart is moving over a horizontal surface at a velocity of 50 cm/sec. It is hit by another cart which is moving in the same direction at a velocity of 150cm/s. After collision the carts continue to move in the same direction at the same velocity of 100 cm/s. Find the ratio of the masses of the carts. 7.NCERT solutions class 11 physics Work,Power and Energy 8.NCERT notes class 11 physics Work,Power & Energy 9.Class 11 physics Work, Power & Energy LearnoHub.comm (formerly called ExamFear Education) is a Free Education platform with more than 6000 videos on Physics, Chemistry, Maths, Biology, English, Science experiments, tips & tricks and motivational videos for Classes 6 to 12.
