Problem: A running mountain lion can make a leap 10.0 m long, reaching a maximum height of 3.0 m.1. What is the speed of the mountain lion just as it leaves the ground?2. At what angle does it leave the ground?

FREE Expert Solution

Uniform accelerated motion (UAM) equations:

 vf = v0 -gty=(vf+v02)ty= v0t-12gt2 vf2= v02 -2gy

(1)

Range = 10.0 m

  • Hmax = 3.0 m
  • vf,y = 0 m/s
  • g = 9.8 m/s2 
  • v0,y = ?
  • t = ?

We'll use the motion in the y-direction to determine v0,y and flight time.

Using the last UAM equation:
