A person standing on a moving truck, throws a stone vertically up relative to himself. To a person, standing on the ground, the stone appears to : (immediately after being thrown).

A

Rise vertically up and come down

B

Rise towards the rear of the truck

C

Move along a parabolic path

D

Rise straight and forward but inclined to the direction of motion of truck

Text Solution

Verified by Experts

The correct Answer is:
c
With respect to the man on ground, the ston has horizontal velocity (equal to that of the truck) as well as vertical velocity. So, it would appear to move along a parabolic path.

    A cart is moving along +x direction with a velocityof 4 m//s . A person on the cart throws a stone with a velocity of 6 m//s relative to himself. In the frame of reference of the cart the stone is thrown in y-z plane making an angle of 30^@ with vertical z-axis. At the highest point of its trajectory, the stone hits an object of equal mass hung vertically from the branch of a tree by means of a string of length L. A completely inelastic collision occurs, in which the stone gets embedded in the object. Determine : (i) The speed of the combined mass immediately after the collision with respect to an observer on the ground, (ii) The length L of the string such that the tension in the string becomes zero when the string becomes horizontal during the subsequent motion of the combined mass.
