Answer:
29 m
Explanation:
given,
speed of the car = 73 Km/hr
= 73 x 0.278 m/s = 20.3 m/s
Time elapses before the motorcycle is moving as fast as the car
using equation of motion
v = u + at
initial speed = 0 m/s
20.3= 0 + 7 x t
t = 2.9 s
b) distance traveled by the car in that time
d = s x t
d = 20.3 x 2.9 = 58.87 m
distance traveled by the police
s = 29.435 m
distance car is ahead = 58.57 - 29.44 = 29.13
= 29 m
