Hi. I need some help. A baseball diamond is a 90 foot square. A player approaches 3rd base at a rate of 28 feet per second at the instant he is 30 feet from 3rd base. Find the rate of change of the player's distance from homeplate. So df/dt= 28 But I don't know where to go from here.

Please help me with this question An outfielder catches a baseball of mass .14kg moving at 50m/s. The glove and ball move .50m during the time the ball is stopped. What is the average force exerted by the ball on the outfielder's glove? At first I thought this questin had to do with F=ma...

My Baseball coach is also my physics instructor. He says that "it is easier to throw a baseball horizontally than it is vertically" -- and that throwing speed varies with elevation angle approximately as: v_0cos(\frac {\theta}{2}) \text{ m/s} \text {where }v_0 = \text{the initial velocity...

A major leaguer hits a baseball so that it leaves the bat at a speed of 31.4 m/s and at an angle of 38.1 above the horizontal. You can ignore air resistance #1: At what two times is the baseball at a height of 10.9s above the point at which it left the bat? Give your answers in ascending...

Heres what the book gives: A baseball player slides into third base with an initial speed of 7.90m/s. If the coefficient of kinetic friction between the player and the ground is 0.41, how far does the player slide before coming to rest. Help? Please? :mad:

I am having difficulty with Problem 79 of Chapter 3 from Physics for Scientists and Engineers by Paul A. Tipler, 4th Edition: The distance from the pitcher's mound to home plate is 18.4 m. The mound is 0.2 m above the level of the field. A pitcher throws a fast ball with an initial speed of...

Baseball and the moon essay... I really need info about baseball and the moon put together. I'm new and I also want to know a little about how many mods and admins there are and the general stuff. I have to do an essay for this summer math and recent technology's camp in Maryland and I really...

can you please help me with this question. I really am stumped, on how to get the initial velocity. A ball player hits a home run and the baseball just clears a wall 21.0 m high located 130 m from home plate. (assume max height of the ball is 21.0 m) The ball is hit at an angel of 35.0* to...

I just need alittle help on getting started with just the formulas. There are just two question. 1) A baseball thrown at 100.8 mi/hr. If the pitch were thrown horizonally with this velocity how far would the ball travel vertically by the time it reaches home plate 60.0 ft away? Do i need...

baseball: how do "sinkers" work? in baseball, many pitchers use a pitch called a "sinker" (not a curveball, but a ball that drops once it gets near the plate) how do they do this? I am assuming they put top spin on the ball to make it curve downward/drop, but how would they put top spin on...

[SOLVED] projectile motion problem Hello guys, This particular problem has been giving me a headache. I can't see how to figure out this problem w/o being given an inital angle. Here it is: A baseball is hit at ground level. The ball reaches its max height above ground level 3 s after...

I have heard a couple of angles on this...so to speak. Is it possible to throw a baseball in such a way as to cause the ball to fall, and then rise due to aerodynamic lift? Baseball players will swear that they do.:wink:

How would you modify the game of baseball in order to play it indoors on the moon? (The game would be played in a structure that would stimulate “earth like” air conditions) Nothing else regarding the moon’s environment would change. Concentrate on what would affect the game, such as the gravity...

How would i modify the game of baseball in order to play indoors on the moon? I have to assume that the game would be played in a structure that would simulate earthlike air conditions but nothing else regarding the moon's environment. i need to know how the differences in gravity on the moon...
