"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?
An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is equal to 2.60 10-28 kg, what is the speed of the heavier fragment
An archer puts a 0.26 kg arrow to the bowstring. An average force of 213 N is exerted to draw the string back 1.3 m. unless otherwise directed, suppose that air resistance is negligible. Illustrate energy bar graphs to solve the problem.
