Answer #1

a) Here I am assuming v is in m/s unit.

Spped is zero twice one at t=0s, and one at t=4.687s

_________________________________________________

b)

for maxima of a(t),

so, t=0,

highest acceleration is, amax=0.15 m/s2 at t=0s.

c)

__________________________________________________________________________

d)

for maxima of v,

t=2.344 s

_______________________________________________________________

e) It will start returning when v=0 at time t=4.687s
