Please explain what you are doing and use calculus NOT PHYSICS! Thanks yall!


An object initially (t=0) at point (0,0,0) and having an initial velocity of <8,0,0> m/s experiences a time-dependent force that gives it an acceleration of <0,4,2t> m/s^2.

a) Find the speed of this object at t=1s.

b) How far has the object travelled in the first second?

c) Find the position of the object at t=1s.

d) Find the tangential and normal components of the acceleration at t=1s.
