Answer:
t = 8.45 sec
car distance d = 132.09 m
bike distance d = 157.08 m
Explanation:
GIVEN :
motorcycle is 25 m behind the car , therefore distance need to covered by bike to overtake car is 25+ d, when car reache distance d at time t
for car
by equation of motion
u = 0 starting from rest
for bike
equating time of both
solving for d we get
d = 132 m
therefore t is
t = 8.45 sec
each travelled in time 8.45 sec as
for car
d = 132.09 m
fro bike
d = 157.08 m
