A car is driving initially at a velocity of 24 m/s. It then changes speed to a velocity of 30 m/s during a 2.7 s time period. How far did it travel during that time? Answer: 72.8 m

Solutions

Expert Solution

U = 24m/s

V = 30m/s

t = 2.7s

From V-U = at

=) a = (30 - 24)/2.7 = 6/2.7 = 2.22223m/s^2

Now from V^2 - U^2 = 2aS

=) S = (900 - 576)/2×2.22223 = 72.8m

=) S = 72.8m
