In a slow-pitch softball game, a 0.200 kg softball crossed the plate at 18.00 m/s at an angle of 45.0° below the horizontal. The batter hits the ball toward center field, giving it a velocity of46.0 m/s at 30.0° above the horizontal.
(a) Determine the impulse delivered to the ball: 10.51 N.s i hat + 7.14 N.s j hat (Assume that the x-axis is positive toward center field and the y-axis is positive upward.)
(b) If the force on the ball increases linearly for 4.00 ms, holds constant for 20.0 ms, then decreases to zero linearly in another 4.00 ms, what is the maximum force on the ball?
A 46.6 ?F capacitor is connected to a 46.7 ? resistor and a generator whose RMS output is 24.4 V at 54.0 Hz. Calculate the phase angle for the circuit
For safety in climbing, a mountaineer uses a nylon rope that is 60 m long and 1.0 cm in diameter. When supporting an 88 kg climber, the rope elongates 1.80 m. Find its Young's modulus.
