Evaluate the magnitude of the acceleration of the mass

Reference no: EM13664108

A 125 g mass starts from rest at the origin (at t = 0) and moves with a velocity of v = 2 t i - t3 j (t is in second and v is in m/s).

a) Find the magnitude of the velocity at t = 2 second?

b) Find the magnitude of the acceleration of the mass at t= 2 second?

c) Find the position of the mass as a function of time, r (t )?

d) Find the magnitude of the force on the mass at t= 2 second?
