Hello can you please help me with this question

1. The vertical displacement of a sport vehicle's body after running over a bump is an example of a dampened harmonic motion and can be modelled by the function h(t) = (e-0.5)(sint), 0 s t s 2m where h is the vertical displacement, in metres, at time t, in seconds. a) Determine h'(t). [1] b) Determine the maximum vertical displacement of the SUV and at what time it occurs. [3]
