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.
The front 1.20 m of a 1 400-kg car is designed as a “crumplezone” that collapses to absorb the shock of a collision. If a cartraveling 25.0 m/s stops uniformly in 1.20 m, (a) how long doesthe collision last, (b) what is the magnitude of the average forceon the car, and (c) what is the acceleration of the car? Expressthe acceleration as a multiple of the acceleration of gravity.
: A wooden ball of weight 196 newtons is dropped vertically from a height of 100 meters above the ground. Throughout the fall, drag is present by a factor 4v due to air resistance, where v is the velocity of the ball at time t (in seconds). After how many seconds will the ball impact the ground? Assume that the net force acting on the ball is modeled by m(dv/dt) = mg - kv, where m is the mass of the ball. Also, assume that there is no initial velocity and that the acceleration due to gravity g is 9.8 meters per second squared.

Upon arriving at work, Michael immediately kicks off a particularlyunfortunate day by hitting an employee with his 1200-kg car and breakingher pelvis. If it takes roughly 4,000 N to crack the average human pelvis,and Michael’s car came to a complete stop after 0.3 seconds ofdeceleration during the collision, how fast was he traveling in the parkinglot when he collided with his employee (let’s call her Meredith)? Assume allthe force of deceleration of his car was exerted on the Meredith’s pelvis,with none being exerted on brakes or opposed by friction (admittedlyunrealistic).

A 2000.0 kg car is slowed down uniformly from 20.0 m/s to 5.00 m/s in 4.00s. What average force was acted on the car during this time? How far did the car travel during this time?
A wooden ball of weight 196 newtons is dropped vertically from a height of 100 meters above the ground. Throughout the fall, drag is present by a factor 4v due to air resistance, where v is the velocity of the ball at time t (in seconds). After how many seconds will the ball impact the ground? Assume that the net force acting on the ball is modeled by m(dv/dt) = mg – kv, where m is the mass of the ball. Also, assume that there is no initial velocity and that the acceleration due to gravity g is 9.8 meters per second squared. Do not round off intermediate steps. Round off the final answer to two decimal places.
Most of us know intuitively that in a head-on colli-sion between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Whyis this? Many people imagine that the collision forceexerted on the car is much greater than that exerted onthe truck. To substantiate this view, they point out that thecar is crushed, whereas the truck is only dented. This ideaof unequal forces, of course, is false; Newton’s third lawtells us that both objects are acted upon by forces of thesame magnitude. The truck suffers less damage because it is made of stronger metal. But what about the two driv-ers? Do they experience the same forces? To answer this question, suppose that each vehicle is initially moving at 8.00 m/s and that they undergo a perfectly inelastic head-on collision. Each driver has mass 80.0 kg. Including the masses of the drivers, the total masses of the vehicles are 800 kg for the car and 4 000 kg for the truck. If the colli-sion time is 0.120 s, what…

Paleontologists estimate that if a Tyrannosaurus rex had tripped and fallen, the ground would have exerted anormal force of approximately 260,000 N on its torso as it landed.Assuming the torso has a mass of 3800 kg, (a) find the magnitudeof the torso’s upward acceleration as it comes to rest. (For comparison, humans lose consciousness with an acceleration of about 7g.)(b) Assuming the torso of a T. rex is in free fall for a distance of 1.46m as it falls to the ground, how much time is required for the torsoto come to rest once it contacts the ground?
