The gravitational force exerted on a baseball is 2.31 N down. A pitcher throws the ball...
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...

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 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...
Now assume that the pitcher throws a 0.145 kg baseball parallel to the ground with a speed of 32 m/s in the +x direction
Now assume that the pitcher throws a 0.145 kg baseball parallel to the ground with a speed of 32 m/s in the +x direction. The batter then hits the ball so it goes directly back to the pitcher along the same straight line. What is the ball's velocity just after leaving the bat if the bat applies an impulse of -8.4 N*s to the baseball? I just cant figure out how to do this problem. Please help!

9. A baseball pitcher throws a 158 g baseball at a velocity of 33 m/s towards home plate. The batter hits the ball, and the velocity of the ball coming off the bat is 46 m/s in the opposite direction of the velocity of the pitch. The bat is in contact with the ball for 0.004 seconds. What is the magnitude in Newtons of the average force applied to the ball? 10. A meterstick is balanced on a fulcrum at...

A pitcher throws a baseball. She releases it so that it is initially moving in the horizontal direction, as shown in the figure that follows. Is the motion of the ball after it leaves her hand projectile motion? Explain. 3. Assuming that air resistance is negligible, sketch the x and y components of the position, velocity, and acceleration of the ball as functions of time on the axes that follow. (Assume that the origin of the coordinate system is at...
