Question

A particle moves along a line with acceleration a( t)= 5+ 2 t . The
velocity after 2 seconds is −10m/sec.
1. Find the initial velocity.
2. Find the velocity at t = 4

Answer 1

To go from the acceleration equation to the velocity equation we need to .....?

Answer 2

Integrate .... can you integrate a(t) = 5 + 2t?

Answer 3

would it be a(t)=t^2+5t+c?

Answer 4

Nice! Where did Peter go?

Answer 5

Then would you just sub in 4 for t and evaluate?
