Acceleration versus time graph of a body in SHM is given by a curve shown below. T is the time period. Then corresponding graph between kinetic energy KE and time t is correctly represented by A. B. C. D. |
Answer» Correct Answer - A From the graph, equation of acceleration can be writtern as `a = - a_(max) cos omegat` `:.` velocity can be written is `v = -v_(max) sin omegat`. `KE = 1/2 mv^(2) = 1/2mv_(max)^(2) sin^(2)omegat` Hence the graph is as shown in A |
