A body of mass 7 kg is projected vertically upward with an initial velocity 32 meters per second.
The gravitational constant is g = 9.8 m/s^2. The air resistance is equal to k*abs(v) where k is a constant.
Find a formula for the velocity at any time ( in terms of k):
v(t) = ?
I'm not really sure how to go about starting this problem. So any help i can get would be appreciated thanks!
