Question

A particle of mass 0·42kg vibrates with a period of 4 seconds. If its greatest displacement is 0·8m, what is the maximum kinetic energy.

Answer 1

Answer:

0.0084J

Step-by-step explanation:

mass-0.42kg

time-4sec

displacement-0.8m

velocity-d/t

           =0.8/4=0.2m/s

kinetic energy=1/2*m*v*v

                      =1/2*0.42*0.04

                       =0.0084J
