The displacement of a particle is given ...

The displacement of a particle is given by `y (t) =2t ^(2) +5m.` Hence its velocity at the end of 6 sec. will be ...... m/s.

A

77

B

4

C

0

D

24

Text Solution

Verified by Experts

The correct Answer is:
D
`y = 2 t ^(2) + 5`
`v = 4t`
`therefore t = 6 sec.` speed
`therefore v = 4 xx 6 = 24m//s`
