A Baseball With A Mass Of 135 G Is Thrown Horizontally With A Speed Of 38 8 M S 87 Mi H At A Bat The Ball Is In Conta 1 (11.65 KiB) Viewed 55 times
The answers I've tried include -11,461.5, 11,461.5, and10,915.71. They were all wrong. The way I tried solving was .135kgx 38.8-(-46.1) / 1.05 x 10^-3 = 10,915.71. I also tried .135 kg x(-46.1 - 38.9) / 0.001 = +/- 11,461.5. However, all 3 answers werewrong. What am I doing wrong here? Thanks.
A baseball with a mass of 135 g is thrown horizontally with a speed of 38.8 m/s (87 mi/h) at a bat. The ball is in contact with the bat for 1.05 ms and then travels straight back at a speed of 46.1 m/s (103 mi/h). Determine the average force (in N) exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming ball to be positive. (Indicate the direction with the sign of your answer.) X
