# 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
