a baseball is hit when it is 3ft above the ground It leaves the
bat with initial speed of 155 ft/sec
A baseball is hit when it is 3 ft above the ground. It leaves the bat with initial speed of 155 ft/sec, making an angle of 16 questions with the horizontal. Assume there is linear drag with a drag coefficient k0.31. The acceleration due to gravity is g-32 ft/sec Answer the following ( sin a)1-k-) equations for linear drag,...

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...

Problem 1 A 0.150 kg baseball pitched at 40.0 m/s is hit on a horizontal line drive straight back at the pitcher at 50.0 m/s. a) If the contact time between bat and ball is 3.90×10−3 s, calculate the magnitude of the force (assumed to be constant) between the ball and bat. b) Determine the direction of the force exerted on a ball. Problem 2 Indicate whether the following statements are true for both inelastic collisions and elastic collisions. a)...

Sam fields a baseball hit to him in the left field. He then throws the ball to third to force out the base runner, Mike. Sam releases the ball 1.80 m above the ground with a vertical velocity of 8 m/s and a horizontal velocity of 25 m/s. At the instant Sam releases the ball, he is 41 m from the third baseman, Charlie, and Mike is 13 m from third base and running at 8 m/s toward third. Assume...

1. A 0.145-kg baseball pitched horizontally at 36.8 m/s strikes a bat and is popped straight up to a height of 58.3 m. If the contact time is 1.30 msms , calculate the magnitude of the average force on the ball during the contact. Calculate the direction of the average force on the ball during the contact. 2. An atomic nucleus initially moving at 360 m/s emits an alpha particle in the direction of its velocity, and the remaining nucleus...

rack of mass 1500 kg moving at 30 m/s is braked suddenly wit 1000-V. How far does the car travel before stopping? th a constant braking force of 10. A baseball batter hits an incoming 45 m/s fastball. The ball leaves the bat at 55 m/s after a ball-on-bat contact time of 0.025 s. What is the force exerted on a 0.15-kg baseball? (choose + direction) 11. A trapeze artist, with swing, weighs 800 N; he is momentarily held horizontal...

please explain the answer
1) Up until now we have always ignored air resistance. We should now add it. Let us just think of simple 1-dimensional problem, dropping a ball of mass m from a height H but 2 with air resistance. We can model the air resistance as a force proportional to the velocity, fair = bv. The coefficient bis a constant. (For this problem you can use calculus textbooks or wolfram alpha to do the calculus.) What are...

1. In Major League Baseball, a typical fastball is pitched at a speed of about 90 mph, or 40 m/s. The batter can perform the remarkable task of completely reversing the direction of this ball and sending it back at about 105 mph, or 47 m/s. Doing this at just the right millisecond to get the ball to go where the batter wants it to go is such an amazing feat that a Yale physicist once jokingly declared that hitting...
