Balancing carefully, three boys inch out onto a horizontal tree branch above a pond, each planning to dive in separately. The third boy in line notices that the branch is barely strong enough to support them. He decides to jump straight up and land back on the branch to break it, spilling all three into the pond. When he starts to carry out his plan, at what precise moment does the branch break? Explain. Suggestion: Pretend to be the third boy and imitate what he does in slow motion. If you are still unsure, stand on a bathroom scale and repeat the suggestion.
A system can have a nonzero velocity while the net external force on it is zero. Describe such a situation.
The third graders are on one side of a schoolyard, and the fourth graders are on the other. They are throwing snowballs at each other. Between them, snowballs of various masses are moving with different velocities as shown in Figure OQ5.3. Rank the snowballs (a) through (e) according to the magnitude of the total force exerted on each one. Ignore air resistance. If two snowballs rank together, make that fact clear.
A device used since the 1940s to measure the kick 01 recoil of the body due to heartbeats is the “ballistocardiograph,” What physics principle(s) are involved here to measure the force of cardiac contraction? How might we construct such a device?
A 0.450-kg hammer is moving horizontally at 7.00 m/s when it strikes a nail and comes to rest after driving the nail 1.00 cm into a board. Assume constant acceleration of the hammer-nail pair. a. Calculate the duration of the impact. b. What was the average force exerted on the nail?
1. During a rescue operation, a 5300-kg helicopter hovers above a fixed point. The helicopter blades sendair downward with a speed of 62 m/s. What mass of air must pass through the blades every second to produce enough thrust for the helicopter to hover?Explain and labled.
1. Determine the impulse exerted in each of the following conditions: a. a dynamics cart experienced a force of 25 N going [East] for a time interval of 3.2 seconds b. a force of 120 N hits a baseball by a bat with a time interval of 0.05 seconds C. a 12 kg rock falling from a cliff for 3.0 seconds
1. A 0.53-kg billiard ball initially at rest is given a speed of12 m/s during a time interval of 4.0 ms. What average forceacted on the ball during this time? Graph and Explain.
A 160 N net force acts right on a 20 kg object. If the initial velocity of the object is 20 m/s right, then what is the final velocity of the object after the net force has acted through a displacement of 50 m right?
A 50.0 kg driver is riding at 35.0 m/s in her red sports car when she must suddenly slam on the brakes to avoidhitting a deer crossing the road. She strikes the air bag, which brings her body to a stop in 0.500 s.a. What average force does the seat belt exert on her? b. If she had not been wearing her seat belt and not had an air bag, then the windshield would have stopped herhead in 0.002 s. What average force would the windshield have exerted on her? c. What is the impulse delivered to her when the air bag changes her momentum? d. What is the impulse delivered to her when the windshield changes her momentum? e. Compare the two impulses calculated in c and d and justify the results.
A 56 g base ball is travelling at 40 m/s. When it hits with the baseball bat, you exert an average force of 78 N, sending the ball back at 30 m/s. How long was the baseball in contact with the bat? Please answer in m/s
