The figure shows a 0.300 kg baseball just before and after it collides with a bat. Just before, the ball has a velocity v1 of magnitude 12.8 m/s and angle θ1 = 35°. Just after, it is travelling directly upward with velocity v2 of magnitude 10.0 m/s. The duration of the collision is 1.60 ms. (a) What is the magnitude of the impulse on the ball from the bat? kg⋅m/s (b) What is the direction (relative to the positive direction of the x axis) of the impulse on the ball from the bat? ° (counterclockwise from the +x axis) (c) What is the magnitude of the average force on the ball from the bat? N (d) What is the direction of this average force? ° (counterclockwise from the +x axis)

We have an infinitely long wire, again with linear charge density λ = 10 μC/m. We have a point charge, again with q = 75 μC. Point S is zS = 10 m away from the wire on the z-axis, point P is zP = 5 m away from the wire on the z-axis, and point T is yT = 5 m away from the wire on the y-axis. Remember that the electric field at a distance r away from a wire is E→wire = 2 kλrr^ Figure 2: Figure for Problems 3-5 3. Potential change with radial path 1 point What is the energy change from point S to point P ? 4. Potential change with angular path 1 point What is the change in energy from point P to point T along the quarter-circle path? 5. Potential change with square path 1 point What is the change in energy from point P to point T along the square path? (Next two questions) We have an infinitely long wire of linear charge density 1 nC/m. You throw a ball with charge Q = −8 C and mass m = 2 kg away from the wire with initial velocity vi = 12 m/s. The ball is initially 4 meters away from the wire. 6. Change in potential 1 point After some time the ball's velocity decreases to 6 m/s, half its initial speed. What is the magnitude of the change in potential, in volts, from the initial position to this position of the ball? 7. Maximum distance 2 points What is the maximum distance the ball gets from the wire?

A girl launches a toy rocket from the ground. The engine experiences an average thrust of 5.26 N. The mass of the engine plus fuel before liftoff is 24.8 g, which includes fuel mass of 12.1 g. The engine fires for a total of 1.90 s. (Assume all the fuel is consumed. ) (a) Calculate the average exhaust speed of the engine (in m/s ). m/s (b) This engine is located in a rocket shell of mass 57.0 g. What is the magnitude of the final velocity of the rocket (in m/s) if it were to be fired from rest in outer space with the same amount of fuel? Assume the fuel burns at a constant rate. m/s
