You throw a basketball from a cliff to the ground. The ball has an initial velocity of 12 m/s in the horizontal direction. After 3.0 seconds, the ball has a velocity of -30.0 m/s in the y-direction. What is the direction of motion of the ball at time t= 3.0 s? (Hint: direction is related to the angle).
Answers: 1
), in sexagesimal degrees, is calculated by this trigonometrical expression:
(1)
- Horizontal velocity, in meters per second.
- Vertical velocity, in meters per second. 
and 
, then the direction of motion of the ball is:
(below the +x semiaxis)

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
