11. A baseball has a mass of 0.3kg. A pitcher pitches the ball and is has a velocity of 12m/s to the left with an angle of 35 degrees below the horizontal. When the bat hits the ball it then moves straight upward with a velocity of 10m/s. The time the ball is in contact with the bat is 2 ms. a) What is the magnitude and direction of the impulse on the ball from the bat? b) What is the magnitude and direction of the average force on the ball from the bat?

Step 1
The initial momentum of the ball can be calculated using the mass and velocity given: Initial momentum = mass * initial velocity = 0.3 kg * 12 m/s (to the left) = -3.6 kg·m/s The final momentum of the ball can be calculated Show more…

A $0.30 \mathrm{~kg}$ softball has a speed of $12 \mathrm{~m} / \mathrm{s}$ at an angle of $35^{\circ}$ below the horizontal just before making contact with a bat. The ball leaves the bat $2.0 \mathrm{~ms}$ later with a vertical velocity of magnitude $10 \mathrm{~m} / \mathrm{s}$ as shown in Fig. $7-23$. What is the magnitude of the average force of the bat on the ball during the ball-bat contact?
A bat strikes a 0.160 kg baseball. Just before impact, the ball is travelling horizontally to the right at 45.0 m/s, and it leaves the bat traveling to the left at an angle of 36.9° above the horizontal with a speed of 60.0 m/s. If the ball and the bat are in contact for 1.75 ms, (a) find the components of the impulse of the net force on the ball. (b) What is the magnitude and direction of the average force on the ball?

The figure shows a 0.3 kg baseball just before and just after it collides with a bat. Just before, the ball has velocity v₁ of magnitude 11.0 m/s and angle θ₁ = 35.7°. Just after, it is traveling directly upward with velocity v₂ of magnitude 9.50 m/s. The duration of the collision is 2.50 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?
