Step 1

The puma will be in a projectile motion. The equation for the maximum height achieved by a projectile is given by help_outlineImage Transcriptioncloseh = 2g Here, his the maximum height reached, v is the initial speed, 0 is the initial angle of launch and g is the acceleration due to gravity Rewrite the above equation for v, 2gh=v sin2 e 2gh sin e 2gh sin e The value of g is 9.80 m/s2 . fullscreen
Step 2

Substitute the numerical values...
