Answer:
(a) Distance traveled = 75.3846 m
(b) Velocity of car at that instant will be 14 m/sec
Explanation:
We have given acceleration of the car
Initial velocity of the cart u = 0 m/sec
(a) According to second equation of motion we know that
So distance traveled by car
As the truck is moving with constant speed
So distance traveled by truck
As the truck overtakes the car
So
So distance traveled
(b) From second equation of motion we know that v = u+at
So v = 0+1.3×10.769 = 14 m /sec
