Question

:) A body of mass 1 kg is performing linear SHM. Its disp cm) at time t (in second) is given by x=6 sin (100t+1/4). Trinetic energy of the body is the maximum kE is​

Answer 1

Explanation:

x=6 sin(100t+1/4)

dx/dt=600 cos(100t+1/4)

V°=600m/s=max.velocity

max.K E=1/2×m×V°^2=1/2×1×600×600=180 kJ
