Answer: 30s, 900m
Explanation: once the break is applied, the car will decelerate and the car will come to rest.
Since the car is coming to rest, final velocity (v) equals zero.
Hence u = 60 m/s, a = - 2m/s²
Recall that v = u + at
0 = 60 +( - 2)t
2t = 60, t = 60 /2 = 30s.
To get the distance covered before the car comes to rest, we have the formulae below
v² = u² + 2as
0² = 60² + 2(-2)s
0 = 3600 - 4s
4s = 3600
s = 3600/ 4 = 900m
