A baseball pitcher throws a ball vertically straight upward and catches the ball 4.9 s later. (calculators permitted in this question) (a) With what velocity did the ball leave the pitcher's hand? v?i = m/s (b) What was the maximum height reached by the ball? h = m
In softball, the pitcher throws underhand with the arm fully extended (straight at the elbow)
In softball, the pitcher throws underhand with the arm fully extended (straight at the elbow). In a fastpitch the ball, of mass m=0.156 kg, leaves the hand at a speed of 139 km / h, when the arm is pointed vertically downward.Part (a) Find the rotational kinetic energy, in joules, of the pitcher's arm-ball system, given that the arm's moment of inertia is 0.72 kg · m2 and the ball leaves the hand at a distance of 0.725 m from...

Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 23 m/s at an angle 28 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground. What is the horizontal component of the ball’s velocity right before Sarah catches it? What is the vertical component of the ball’s velocity right before Sarah catches it? What is the time the ball...

* Problem 11 - Free fall motion (20 points) You throw a ball vertically upward from the flat roof of a tall building. The ball leaves your hand at a point even with the roof railing, with an upward velocity of 12 m/s. On its way back down, it just misses the railing. Find (a) the position and velocity of the ball 1.5 s and 5 s after it leaves your hand; (b) the velocity of the ball when it...

A ball is thrown straight up such that it leaves your hand with 200 Joules of kinetic energy. Suppose we choose the ball + Earth as our system and we use the height of the ball when it leaves your hand as h = 0. Answer the questions below ignoring air resistance. Initial gravitational potential energy when the ball leaves your hand = Kinetic energy when the ball is half way to its maximum height = j. Gravitational potential energy...

9). A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is ?0=2.75 m/s. Knowing that at the time of the release the balloon was 58.3 m above the ground, determine the time ? it takes for the bag to reach the ground from the moment of its release. Use ?=9.81 m/s2. r= 10) You throw a baseball directly upward at time ?=0 at an initial speed of 14.1 m/s. What is the maximum height...
