MY NOTES ASK YOUR TEACHER An 8.5 g bullet with a speed of 750 m/s is shot into a wooden block and penetrates 27 cm before stopping. What is the average force (in N) of the wood on the bullet? Assume the block does not move. (Enter the magnitude.) l N 12. OSUNIPHYS1 7A.P.071. ASK YOUR TEACHER (a) What is the average useful power output (in w) or a person who does 6.60 x 106 J of useful work in 7.60 h? w (b) Working at this rate, how long (in s) will it take this person to lift 1700 kg of bricks 1.70 m to a platform? (Work done to lift his body can be omitted because it is not considered useful output here.) 5 13. OSUNIPHYS1 8.1.WA.005. ASK YOUR TEACHER A pendulum bob With a mass or 0.300 kg is attached to a 1.5 m long string as shown. As the pendulum bob swings from point A, where the angle 0 = 390, to point B at the bottom of its arc, determine the change in the gravltatlonal potential energy of the pendulum bobrearth system.
