Question

A particle is at position 3ti+4t^3 j.Calculate the velocity of particle at time t =4​

Answer 1

Answer:

Velocity at t = 4s is 3i + 192j

Explanation:

Given that,

Position = S = 3ti + 4t³j

dS/dt = v = 3i + 4*3t² j

v = 3i + 12t²j

Therefore, putting t = 4 in the equation of velocity we get,

v = 3i + 12*16 j

v = 3i + 192j
