A baseball pitcher throws a baseball horizontally at a linear
speed of 42.5 m/s (about 95 mi/h). Before being caught, the
baseball travels a horizontal distance of 15.3 m and rotates
through an angle of 52.1rad. The baseball has a radius of 3.67 cm
and is rotating about an axis as it travels, much like the earth
does. What is the tangential speed of a point on the "equator" of
the baseball?

A baseball pitcher throws a baseball with a speed of 45 m/s . In throwing the baseball, the pitcher accelerates the ball through a displacement of about 3.5 m, from behind the body to the point where it is released as shown in (Figure 1) . Estimate the average acceleration of the ball during the throwing motion. Express your answer using two significant figures.
A baseball has a velocity of 42.5 m/s (95.1 mi/h), directed horizontally, as it is released by a pitcher. The ball's velocity 0.0100 s before it is released is 41.1 m/s, directed 4.50° above the horizontal. Calculate the ball's instantaneous acceleration just before it is released. magnitude: direction _____ below the horizon.
A baseball pitcher throws a baseball with a speed of 42 m/s . What is the de Broglie wavelength of the baseball, given that a standard baseball has a mass of 145 grams?
When a pitcher throws a baseball or softball, the rotation speed is important when it comes to making the ball "break," or curve away from its expected motion. A softball that has a mass of 0.200 kg and a radius of 4.77 cm can rotate at a rate of 1.4410pm on its way to home plate, causing the ball to curve! Suppose this softball is rotating around an axis through its center at this extreme rate. What is the rotational...
A pitcher throws a 0.143-kg baseball toward the batter so that it crosses home plate horizontally and has a speed of 42 m/s just before it makes contact with the bat. The batter then hits the ball straight back at the pitcher with a speed of 51 m/s. Assume the ball travels along the same line leaving the bat as it followed before contacting the bat. (a) What is the magnitude of the impulse delivered by the bat to the...
A pitcher throws a 0.138-kg baseball toward the batter so that it crosses home plate horizontally and has a speed of 42 m/s just before it makes contact with the bat. The batter then hits the ball straight back at the pitcher with a speed of 46 m/s. Assume the ball travels along the same line leaving the bat as it followed before contacting the bat. (a) What is the magnitude of the impulse delivered by the bat to the...
a baseball pitcher throws a baseball (145 grams) towards the batter at a speed of 35 m/s. the batter swings her bat (940 grams) with an unknown speed towards the ball. the bat hits the ball, and the ball goes flying back toward the pitcher at a higher speed. if the ball's speed (not velocity) increases by about 20% and the bat's speed decreases by about 50%, what was the initial speed of the bat before it hit the ball?...
A baseball pitcher throws a 145 g baseball parallel to the ground with a speed of 27.31 m/s in the +x direction. The batter imparts an impulse of –10.43 to the ball so that the ball returns along the same path in the –x direction. What is the velocity of the ball after leaving the bat?
7. A baseball pitcher throws a ball at 92.0 mi/h in the horizontal direction. How far does the ball fall vertically by the time it reaches home plate, which is a horizontal distance of 60.5 ft away? (Express your answer in units of feet. Neglect air resistance.) 8.A panther jumps to a height of 2.50 m when leaving the ground at an angle of 41.9º. What is its initial speed (in m/s) as it leaves the ground? 9.A bowling ball is launched from...
The gravitational force exerted on a baseball is 2.00 N down. A pitcher throws the ball horizontally with velocity 12.0 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 200 ms. The ball starts from rest.
