Leilani Mitchell of the Washington Mystics is 5 ft 5 inches and when she makes a free throwthe ball leaves her hand about 2 m above the ground. The center of the hoop is 4.3 m awayin the horizontal direction and 3.1 m above the ground. Treat the ball as a point particle (ignore the radius of the ball) and neglect air resistance. (A) If the ball takes t = 0.7 seconds to go from her hand to the hoop, find the magnitude and direction of the velocity with which it leaves her hand.
(B) Find the magnitude and direction of the velocity of the ball as it goes through the hoop

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
