A solid cylinder rolls from the back of a large truck travelling at `10 m//s` to the right. The cylinder is travelling horizontally at `8m//s` to the left relative to an observer in the truck. The solid cylinder lands on the roadway `1.25m` below its starting level. How far behind the truck does it land (in `m`)?

Text Solution

Verified by Experts

The correct Answer is:
D
`1.25=1/2(10)t^(2)`
`:.t=0.5` sec
Distance of the cylinder from the truck `=8xx0.5=4m`
