7. how long would it take a leopard running at 9 m/s to cover 32m?

3.6 s

Explanation:

The leopard is moving by uniform motion (constant velocity), therefore we can use the equation

where

v is the speed of the leopard

d is the distance covered

t is the time taken

Here we have:

v = 9 m/s is the speed

d = 32 m is the distance that the leopard has to cover

Solving for t, we find the time needed for the leopard to cover the 32 m:

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

d is the correct answer
