Question1

A 575g air-track glider attached to a spring with spring constant 14.0 N/m is sitting at rest on a frictionless air track. A 225 g glider is pushed toward it from the far end of the track at a speed of 84.0 cm /s. It collides with and sticks to the 575g glider.

a. What is the amplitude of the subsequent oscillations?

b. What is their period?

Question2

A baseball thrown at an angle of 25 degree relative to the ground at a speed of 23.0m/s if the ball was caught 42.0 m form the thrower how long was it in the air? How high was the tallese spot in the falls path?

Question3
