Abaseball approaches home plate at a speed of 40.0 m/s, moving horizontally just before being hit by a bat. the batter hits a pop-up such that after hitting the bat, the baseball is moving at 56.0 m/s straight up. the ball has a mass of 145 g and is in contact with the bat for 1.90 ms. what is the average vector force the ball exerts on the bat during their interaction? (let the +x-direction be in the initial direction of motion, and the +y-direction be up.)

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

A58-kg boy swings a baseball bat, which causes a 0.140-kg baseball to move toward third base with a velocity of 38.0 m/s.
