mass * (velocity change) = impulse The velocity changes from +3.8 to -5.2 so the velocity change is 9.0 m/s. (The direction change is important) Mass = 0.7 N-s/9.0 m/s = 0.0778 kg = 77.8 g (The official mass of a Major League baseball is 145 g, so they did a poor job dreaming ...

I take it that this is 0.85% w/v. If so, that means 0.85 g NaCl per 100 mL solution. Convert 0.85 g NaCl to moles. moles = grams/molar mass = 0.85/58.5 (you may want to refine this figures) = 0.0145 moles/100 mL which is 0.145 moles/L soln which is 0.145 M or 0.145 N.

math
is there a common multipple for 116, and 145? Can 116/145 be reduced or simplified? I have been agonizing for an hour over this. Please show me the answer.

A 0.145 kg baseball pitched at 35.0 m/s is hit on a horizontal line drive straight back toward the pitcher at 52.0 m/s. If the contact time between bat and ball is 1.00*10 to the -3, calculate the average force between the ball and bat during contact.

Physics
A 0.145 kg baseball pitched at 37.5 m/s is hit on a horizontal line drive straight back toward the pitcher at 48.0 m/s. If the contact time between bat and ball is 3.50×10^−3 s, calculate the average force between the ball and bat during contact.
