In a slow-pitch softball game, a 0.200-kg softball crosses the plate at 12.0 m/s at an angle of 35.0° below the horizontal. The batter hits the ball toward center field, giving it a velocity of 48.0 m/s at 30.0° above the horizontal. (Take positive i to be the horizontal direction from the plate toward center field and take positive j to be the upward vertical direction.) (a) Determine the impulse delivered to the ball 11.99 (b) If the force on...

A pitcher throws a 0.200 kg ball so that its speed is 18.0 m/s and angle is 40.0° below the horizontal when a player bats the ball directly toward the pitcher with velocity 46.0 m/s at 30.0° above the horizontal. Assume ti to be along the line from the batter to the pitcher and +j to be the upward vertical direction. (Express your answers in vector form.) (a) Determine the impulse (in N...

2. Two steel balls are colliding elastically. Ball 1 has a mass of 1.20 kg and is moving 3.00 m/s at an angle of 45 degrees measured from the positive X-axis before the collision. Ball 2 has a mass of 1.50 kg and is moving 2.50 m/s at an angle of 60 degrees above the negative X- axis before the collision. Assume the balls hit squarely without a glancing blow so the balls can roll in the direction calculated normally....

Problem 4 (25 points) The figure below shows a mass spectrometer, a device used to measure the masses of ions. Consider a positive ion of unknown mass m and charge q = 3.2 x 10-19 C. The ion is first accelerated from rest through a potential difference of magnitude 1v1 = 750 V inside a source. After leaving the source, it travels upward at constant speed and enters a region of uniform magnetic field B = 2.5 T directed out...
