A golf ball reaches a height of 150 m before it stops rising and starts to fall to the ground. What is the golf balls speed (rou
artcher [175]

Answer:

v = 54 m/s

Explanation:

Given,

The maximum height of the flight of golf ball, h = 150 m

The velocity at height h, u = 0

The velocity of the golf ball right before it hits the ground, v = ?

Using the III equations of motion

                               <em>  v² = u² + 2gh</em>

Substituting the given values in the above equation,

                                 v² = 0 + 2 x 9.8 x 150 m

                                     = 2940

                                  v = 54 m/s

Hence, the speed of the golf ball right before it hits the ground, v = 54 m/s

Unlike an observational study, an experiment can prove:
Zinaida [17]

A. Cause and effect.

Explanation:

An experiment can prove cause and effect in a study unlike observational studies.

  • Observational studies is a non-experimental system of investigation.
  • It helps to identify the causes(independent variable) and the effect(dependent variables).
  • In observational studies, the variables cannot be controlled and so it is difficult to prove the cause and effect.
  • An experiment can prove cause and effect because the parameters are tested and can be controlled.
