A body moves in a straight line along Y-axis. Its distance y in metre) from the origin is given `y = 8t -3t^(2).` The average speed in the time interval from `t =0` second to `t =1` second is

A

`-4ms^(-1)`

B

zero

C

`5ms^(-1)`

D

`6ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`bar(v) = ((8 xx 1 - 3 xx 1 xx 1)-0)/(1) = 5ms^(-1)`
