Constant A spring loaded gun (with a spring constant, k) is compressed. It launches a ball of mass, m, directly upwards. At height, h, the ball is recorded as having a velocity of v. V h Part A The spring in the gun was compressed by a length, x, given by: 2mgh x = k x = m(v²+2gh) x = k 2m(v²+gh) x =

7) A 5-kg body A is released from rest on a frictionless circular surface. The body then moves on a horizon- tal surface CD whose coefficient of friction with the body is 0.2. A spring having a spring constant K = 900 N/m is positioned at C shown in the diagram. How much will the spring compress? K -10 m- 7 m 8) For the system in Question 7, what is the velocity of block A each time it passes point D? 9) For the pendulum in Question 7, what is the maximum normal acceleration of the block?
