The distance travelled by an object along the axes are iven by ` x= 2 t^2 , y=t^2-4 t, z=3 t -5`. The initial velocity of the particle is .

A

10 units

B

12 units

C

5 units

D

2 units

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(x) =4t,v_(y) = 2t = 4, v_(z) = 3`
At `t = 0, v_(x) = 0, v_(y)- 4` and `v_(z) = 3`
`:. V = sqrt(v_(y)^(2)+v_(z)^(2)) =5` units
