The figure shown a particle sliding on a frictionless track, which teminates in a straight horizontal section. If the particle starts slipping from the point `A`, how far away from the track will the particle hit the ground?

A

1m

B

2m

C

3m

D

4m

Text Solution

Verified by Experts

The correct Answer is:
A

`mg(1)=(1)/(2)mv^2+mg(0.5)`
`v^2=2g(1-0.5)=g=10`
`0.5=(gx^2)/(2v^2)=(10x^2)/(2(10))`
`x^2=1impliesx=1m`
