일반물리학 1 — Center of Mass and Linear Momentum: Problem 33

33 Figure 9-43 shows a 0.300 kg baseball just before and just after it collides with a bat. Just before, the ball has velocity \(\vec{v}_1\) of magnitude 12.0 m/s and angle \(\theta_1 = 35.0^\circ\). Just after, it is traveling directly upward with velocity \(\vec{v}_2\) of magnitude 10.0 m/s. The duration of the collision is 2.00 ms. What are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the impulse on the ball from the bat? What are the (c) magnitude and (d) direction of the average force on the ball from the bat?
