In the question number 62, the distance from the thrower to the point where the ball returns to the same level is

A

58 m

B

68 m

C

78 m

D

88 m

Text Solution

Verified by Experts

The correct Answer is:
C
The dsitance from the thrower to the point where the ball returns the same leve is
`R=(u^(2)sin2theta)/(g)=((30ms^(-1))^(2)(sin60^(@)))/(10ms^(-2))~~78`
