Question

A 58-kg ice skater (this value includes her body, her clothing, and several 1.0-kg snowballs she is carrying) is at rest on the ice. She throws a snowball to the right at 15 m/s.

A. What is her speed after the throw?

Express your answer with the appropriate units. Enter positive value if her velocity is to the right and negative value if her velocity is to the left.

What is the coefficient of restitution for this event?

0.93

it approaches infinity

it approaches zero

0.50

She next throws a second snowball but this time at a speed of 30 m/s to the left. What is her speed after this throw?

Express your answer with the appropriate units. Enter positive value if her velocity is to the right and negative value if her velocity is to the left.

What is the coefficient of restitution for this event?

0.50

it approaches infinity

0.93

it approaches zero

Calculate the change in kinetic energy in the second event.

Express your answer with the appropriate units.

Expert Solution

Step 1

Since you have posted a question with multiple sub parts, we will provide the solution only to the first three sub parts as per our Q&A guidelines. Please repost the remaining sub parts separately.

To calculate the velocity of the skater after throwing the snowballs and the coefficient of restitution of the two events

Given:
Mass of the ice-skater including the snowballs: $m = 58 kg$
Mass of each snowball: $m_{S} = 1.0 kg$
Speed of the first snowball: $v_{S 1} = 15 m/s$ to the right
Speed of the second snowball: $v_{S 2} = 30 m/s$ to the left

To calculate:
A. The velocity of the skater after throwing the first snowball: $v_{1}$
B. The coefficient of restitution of the event: $e$
C. The velocity of the skater after throwing the second snowball: $v_{2}$

According to the law of conservation of momentum, the total initial momentum is equal to the total final momentum.
