Academics

During a cheerleading routine, Chris throws his partner Teresa into the air by applying an average force of 1000 N over 1s. If Teresa's mass is 50 kg and she is standing still prior to Chris throwing her

1. What is the vertical velocity of Teresa when Chris releases her in the air?

2. Assuming the initial height he throws her from is 1m off the ground, how much average force would Chris have to apply to get Teresa to a maximum height of 2m off the ground?
