Tom and Dick are running forward with the same speed. They are following a rubber ball to each other at a constant speed v as seen by the thrower. According to Sam who is standing on the ground the speed of ball is

A

Same as v

B

Greater than v

C

Less than v

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Running speed will be added to v .
Let `vecV_(BG)` be the velocity of ball with respect to ground, Vbt be the velocity of ball with respect to thrower and `vecV_(tg)` be the velocity of thrower w.r. to ground. Then, `vecV_(BG) =vecV_(BT) + vecV_(TG)` here, `vecV_(TG) gt 0` . Hence, velocity of the ball with respect to ground will be greater than velocity of ball with respect to thrower.
