Atoy cannon uses a spring to project a 5.28-g soft rubber ball. the spring is originally compressed by 4.99 cm and has a force constant of 8.08 n/m. when the cannon is fired, the ball moves 15.2 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.032 2 n on the ball.
a)with what speed does the projectile leave the barrel of the cannon?
b)at what point does the ball have max speed?
c)what is the maximumspeed.

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?
