Wile E. Coyote is chasing the roadrunner and falls off a cliff. It takes Wile E Coyote 7 long seconds to hit the ground. How high is the cliff (m)?

240.1m  

Explanation:

Given parameters:

Time taken to hit the ground  = 7s

Unknown:

Height of the cliff = ?

Solution:

To solve this problem, we use the right motion equation expressed below:

             S = ut + gt²

S is the height of the cliff

u is the initial velocity  = 0m/s

g is the acceleration due to gravity  = 9.8m/s²

t is the time taken

Now, insert the parameters and solve the problem;

      S = (0 x 7) + (  x 9.8 x 7²)

     S = 240.1m

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
