Question

Calculate the final kinetic energy of a block of mass if the mass of the block is 10 kg and has a constant velocity of 10 m/s. The block of mass is subjected to a retarding force of F=0.1 J/m

Answer 1

Answer:

Hey you typed wrong question check your question

A bolck of mass 10kg is moving in x-direction with a constant speed of 10m/s. it is subjected to a retardeng force F=−0.1xJ/m. During its travel from x=20m to x=30m. Its final kinetic energy will be .

Answer is 475J.
