A ball with an initial velocity of 7.91 m/s rolls up a hill without slipping. (a) Treating the ball as a spherical shell, calculate the vertical height (in m) it reaches. m (b) Repeat the calculation (in m) for the same ball if it slides up the hill without rolling. m
(A) A ball with an initial velocity of 7.7 m/s rolls up a hill without slipping. Treating the ball as a spherical shell, calculate the vertical height it reaches.
(10%) Problem 5: A ball with an initial velocity of 5.5 m/s and mass 2.5 kg moves at an angle 68° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 68° above the horizontal, moving in the opposite direction with the same speed. See the figure. е 4 What was the magnitude of the impulse delivered by the wall, in kilogram meters per second? Grade Summary Deductions Potential 100% E sin cos...

(11%) Problem 9: A heart defibrillator being used on a patient has an RC time constant of 10.5 ms due to the resistance of the patient's body and the capacitance of the defibrillator. Randomized Variables t= 10.5 ms C = 7.5 F V=14 kV ► A50% Part (a) If the defibrillator has an 7.5 UF capacitance, what is the resistance of the path through the patient in k2? (You may neglect the capacitance of the patient's body and...
(9%) Problem 3: A bicyclist notes that the pedal sprocket has a radius of rp = 9.5 cm while the wheel sprocket has a radius of rw = 6.5 cm. The two sprockets are connected by a chain which rotates without slipping. The bicycle wheel has a radius R = 64 cm. When pedaling the cyclist notes that the pedal rotates at one revolution every t= 1.4 s. When pedaling, the wheel sprocket and the wheel move at the same...
