A person is standing on a truck moving with a constant velocity of 14.7 m/s o a hrozontal road. The man throws a ball in such a way that it returns to the truck after the truck has moved 58.8 m. Find the speed and the angle of projection. a. as seen from the truck b. as seen fromt the road.

A

19.6 m/s

B

9.8 m/s

C

4.9 m/s

D

2.25 m/s

Text Solution

Verified by Experts

`?" Time of flight "=(58.8)/(14.7)=4 sec.`
`?" Speed of ball as seen from the truck "=("gt")/(2) =(9.8xx4)/(2) =19.6 m//s`
