Physics Numerical Acceleration!?
The velocity of a Bus is reduced uniformly from 15 m/s to 7 m/s while traveling a distance of 90 m.
i. Compute the acceleration.
ii. How much further will the Bus travel before coming to rest, provided the acceleration remain constant?

(i) v² = u² + 2ad
(7 m/s)² = (15m/s)² + 2 * a * 90m
a = -0.98 m/s²
(ii) Same equation: now 0² = (7m/s)² - 2 * 0.98m/s² * d
d = 25 m
