A catcher gives w/ the ball when he catches a 0.127kg ball baseball moving at 34m/s.If he moves his glove a?
Q continued : distance of 5.77cm. what is his avg force acting on his hand ? aws in units of kN/ b)repeat for the case in which his glove and hand move 12cm . aws in units of N
please i need the awnser and a clear description of the method to solve.
Convert cm to m
5.77 cm = 0.0577 m
Find the acceleration of the glove
Use vf^2 = vi^2 + 2*a*d
a = -vi^2 / (2*d)
Then you can simply use F = m*a = - m*vi^2/(2*d) = -0.127*(34^2) / (2 * .0577)
Plug and chug.
