Answer 1

Answer:

s. at t=0 will be 0m as by applying differentiation to the displacement we can get the initial velocity

Explanation:

initial velocity at t=0 will be 20m/s

then double differentiate the displacement will give the acceleration i.e -30m/s2

now apply s=ut+0.5 a(t)2.......(1)

put the values and for t=0 it will be =0

t=6 it will be -320m
