In preparation for shooting a ball in a pinball machine, a spring (k = 730 n/m) is compressed by 0.0796 m relative to its unstrained length. the ball (m = 0.0585 kg) is at rest against the spring at point a. when the spring is released, the ball slides (without rolling). it leaves the spring and arrives at point b, which is 0.256 m higher than point a. ignore friction, and find the ball's speed at point b.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
