A baseball player is 125 m away from home plate when he throws the ball at a 30 degree angle above horizontal from a height of 1.75 m (the height of his hand) sketch coordinate system a) what is the initial speed of the throw for the ball to land exactly on the home plate? b) how long does it take for the ball to get to home plate? c) what is the maximum height the ball is above the...
A baseball pitcher throws a ball at 92.0 mi/h in the horizontal direction
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 Finnish sport of pesäpallo is similar to baseball with some interesting variations, one of which is that the ball is pitched vertically upward above home plate to a height of at least 1 m over the head of the pitcher and is struck by the batter as it falls toward the ground. If a pitcher releases the ball from a height of 1 m above the ground and it reaches a height of 4 m above the ground, calculate...

A baseball is hit by the batter when the ball is 2.5 feet above the ground. The ball leaves the bat with a velocity of 85 miles per hour at an angle of 50° above the horizontal. a. What is the maximum height of the baseball? b. When does the baseball reached its maximum height? c. If the ball does not hit anything, how many seconds is the ball in the air? d. If the ball does not hit anything,...

The gravitational force exerted on a baseball is 2.31 N down. A pitcher throws the ball horizontally with velocity 14.0 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 157 ms. The ball starts from rest. (a) Through what distance does it move before its release? m (b) What are the magnitude and direction of the force the pitcher exerts on the ball? (Enter your magnitude to at least one decimal place.) magnitude N...

Question 4 of 20: Select the best answer for the question 4. A baseball pitcher throws a baseball with an initial velocity of 128 foot per second at an angle of 20 to the horizontal. The ball leaves the pitcher's hand at a height of 4 feet. Find parametric equations that describe the motion of the ball as a function of time. How long is the ball in the air? When is the ball at its maximum height? What's the...

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 0.200 kg ball so that its speed is 18.0 m/s and angle is 40.0° below the horizontal when a player bats the ball directly toward the pitcher with velocity 46.0 m/s at 30.0° above the horizontal. Assume ti to be along the line from the batter to the pitcher and +j to be the upward vertical direction. (Express your answers in vector form.) (a) Determine the impulse (in N...
