Question

Crickets Chirpy and Milada jump from the top of a vertical cliff. Chirpy just drops and reaches the ground in 3.20 s , while Milada jumps horizontally with an initial speed of 90.0 cm/s .

1. How far from the base of the cliff will Milada hit the ground? Ignore air resistance.
Express your answer with the appropriate units.

Answer 1

Milada will hit the ground 2.88 m from the base of the cliff.

Step-by-step explanation:

To determine how far Milada will hit the ground, we need to find the horizontal distance she will travel. Since she jumps horizontally with an initial speed of 90.0 cm/s, her horizontal velocity remains constant throughout the jump. We can use the equation d = vt to find the distance, where d is the distance, v is the velocity, and t is the time.

We know that the time it takes for Chirpy to reach the ground is 3.20 s, so this will also be the time it takes for Milada to hit the ground. Substituting the values into the equation, we have d = (90.0 cm/s)(3.20 s) = 288 cm.

Therefore, Milada will hit the ground 288 cm (or 2.88 m) from the base of the cliff.
