How much force (in Newtons) does a baseball pitcher ..?
How much force (in Newtons) does a baseball pitcher have to exert on a 250g baseball to make it accelerate to 50 m/s the instant that it leaves his hand?
A. 0.125
B. 0.250
C. 12.5
D. 25.0
E. 50.0
There is something wrong with how the problem is worded. What does "to make it accelerate to 50 m/s ... " mean? Does this mean that the ball speeds up from 0 to 50 m/sec at a given time interval before it is released by the pitcher?
However, based on the options of the answers given, it seems to appear that the figure of "50 m/sec" is really the acceleration of the ball as it leaves the pitcher's hand.
Does anyone know how many ounces the verdero baseball bat is? Is it a "-3" or a "-2"?
This is the bat i am talking about. http://www.baseballexp.com/Baseball-Bats/Wood-Baseball-Bats/Verdero-Game-Stock-Ash-Wood-Baseball-Bat/baseball/lev/6/productId/7338/Ne/1100001/parentCatId/23/pCategoryId/1/Ns/CATEGORY_SEQ_23%7C0/N/36+1100006+33/PIPELINE_SESSION_ID/f8449bc5c0a869662eed52f56894334d/Nty/1/categoryId/1100006/view/85/index.pro
