A projectile is thrown from a point in a horizontal plane such that the horizontal and vertical velocities are `9.8 ms^(-1)` and `19.6 ms^(-1)`. It will strike the plane after covering distance of

A

4.9m

B

9.8m

C

19.6m

D

39.2m

Text Solution

Verified by Experts

The correct Answer is:
D

`R=u_(x)T=u_(x)xx(2u_(y))/(g)=(2xx9.8xx19.6)/(9.8)=39.2m`
