Question

calculate the kinetic energy and potential energy at each point mentioned if the mass of a girl is 50 kg take grams as 10 Newton
pls answer me ​

Answer 1

Answer:

At topmost point--- 》potential energy = mgh(maximum) and Kinetic energy= 0

At bottom----》 Potential energy = 0 Kinetic energy= 1/2mv²

Explanation:

At topmost point potential energy = 50×9.8×h= 490h (given height from the surface of the earth has to put in the value of h)

Kinetic energy = 0

At bottom potential energy =0 Kinetic energy = 1/2 mv² or mgh( according to law of conservation of energy ) So Ke= 490h
