A particle is projected form a trolley car with a velocity `vecv`. If the trolley can moves with an acceleration `veca` towards right, which of the following remain unchanged relative to both ground and trolley car?

A

Range

B

Maximum range

C

Time of flight

D

horizontal velocity

Text Solution

Verified by Experts

The correct Answer is:
c
Vertical component of projectile relative to trolley,
`v_(yT)=v sin theta`
And vertical component of projectile relative to ground
`v_(yG)= v sin theta`
Vertical component is unchanged relative to trolley and ground. Now time of flight`=(2u sin theta)/g`
Time of flight remains unchanged relative to trolley & ground. Hence right choice is (a).

    A trolley was moving horizontally on a smooth ground with velocity v with respect to the earth. Suddenly a man starts running from rear end of the trolley with a velocity (3//2)v with respect to the trolley. After reaching the other end, the man turns back and continues running with a velocity (3//2)v with respect to trolley in opposite direction. If the length of the trolley is L, find the displacement of the man with respect to earth when he reaches the starting point on the trolley. Mass of the trolley is equal to the mass of the man.
