A projectile is thrown from a point in a horizontal plane such that its horizontal and verticaly velocity components are 9.8 and 19.6 m `s^(-1)` respectively. It strikes the ground after covering a horizontal distance of :

A

39.2 m

B

19.6 m

C

9.8 m

D

4.9 m

Text Solution

Verified by Experts

The correct Answer is:
A
Here we are given
`ucostheta=9.8,usintheta=19.6` and
`R=(2usintheta.ucostheta)/9.8=39.2`m
