An 87.6 g lead ball is dropped from rest from a height of 7.00 m. the collision between the ball and the ground is totally inelastic. assuming all the ball's kinetic energy goes into heating the ball, find its change in temperature.

Taking specific heat of lead as 0.128 J/gK = c

We have energy of ball at 7.00 meter height = mgh =

When leads gets heated by a temperature ΔT energy needed = mcΔT

                                                                      = ΔT

Comparing both the equations

                      = ΔT

                        ΔT = 0.536 K

                        Change in temperature same in degree and kelvin scale

                                      So ΔT = 0.536

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
