Answer:
(i) v = 44 m/s
(ii) a = 72 m/s^2
Explanation:
You have the following equation for the potion of a car:

(i) The instantaneous velocity is the derivative of x in time:

for t = 1 is:

(ii) The instantaneous acceleration is the derivative of the velocity:

for t = 1

Answer:
60m/s
Explanation:
initial energy = final energy
g.p.e = k.e
k.e = 0.5 × mass × velocity²
g.p.e = 990000J as per Question
990000Nm = 0.5 × 550 × V²
V² = 3600
V = 60m/s
