Let us suppose police car and motorist travel in straight line and police car catches motorist after s distance
Distance travel by motorist
----1
Distance traveled by Police car
----2
from 1 & 2 we get
(a)Velocity of Police car after t sec
(b)time taken by police car is
(c)Distance travel by police car
Answer:
0.51
Explanation:
m = Mass = 70 kg
g = Acceleration due to gravity = 9.81 m/s²
t = Time taken
u = Initial velocity = 80 km/h = 80/3.6 = 22.22 m/s
v = Final velocity
a = Acceleration
s = Displacement = 50 m
Kinetic coefficient of friction between the road and the crate is 0.51
