A child's play rifle uses a spring to fire a 5.21-g soft plastic ball. The spring is compressed by 4.99 cm and has a spring constant of 7.94 N/m. When the rifle is fired, the ball moves 14.1 cm through the horizontal barrel of the rifle, and the barrel exerts a constant friction force of 0.032 7 N on the ball.

(a) With what speed does the ball leave the barrel of the rifle?

Make certain you have correctly converted all of the centimeter and gram quantities to MKS units. m/s

(b) At what point does the ball have maximum speed?

The maximum speed does not occur at the equilibrium point of the spring, because the friction force is also present throughout the motion. cm (from its original position)

(c) What is this maximum speed?

Using only the spring gun with the catcher removed, fire the steel ball, making sure the launch velocity is horizontal. Using carbon paper (and something to catch the ball after impact with the floor), determine the ball’s horizontal range and its total vertical displacement (i.e., height at point of firing). Repeat several times in order to obtain statistical data. Derive a formula in symbolic form for the initial velocity of the projectile in terms of the following three quantities only:...

A 200 g solid plastic ball (i.e., an insulator) with a 30 cm radius has a total charge of -20 μC that is uniformly distributed throughout its volume. The center of the ball is at the origin. A –5 μC point charge with a mass of 30 g is placed on the x-axis, 100 cm away from the center of the ball. Both charged objects are held in place. a) Find the electric field (magnitude and direction) at the following...
