1. if during a 60 second jog, my average velocity is 5 m/s, how far from my starting point do i end up(what is my displacement ) in meters 2. an hippo falls out of a plane, it accelerates towards the ground at a rate of 10 m/s^2. The hippos mass is 5,000kg. What is the net force being exerted on the hippo as it falls (In newtons)

3. i throw a ball straight up with a force of 5N, gravity then exerts a force of 2.5N down on the ball. The ball's mass is 0.5kg, what is the acceleration of the ball
