A particle is moving along straight line...

A particle is moving along straight line with initial velocity `+7m//sec` and uniform acceleration `-2m//sec^(2)` . The distance travlled by the particle in `4th` second of its motion is:

A

`0`

B

`0.25m`

C

`0.5m`

D

`7m`

Text Solution

Verified by Experts

The correct Answer is:
C
A particle………
Distance travelled `= |S_(3-3.5)|+|S_(3.5-4)|`
`|(1+0)/(2)xx0.5|+|(0+(-1))/(2)xx0.5|=0.25+0.25`
`= 0.5m`.
