Rocket sleds were used to test aircraft and its effects on human subjects at high speeds. It is consisted of four rockets; each rocket creates an identical thrust T. Calculate the magnitude of force exerted by each rocket (T) for the four-rocket propulsion system shown in the Figure. The sled's initial acceleration is 49 m/s, the mass of the system is 2100 kg, and the force of friction opposing the motion is known to be 650N. Solution: H.W Free-oody dagran 1.

In a soccer match against Mexico in 2014, US Women’s National Team striker Alex Morgan scored a sweetheaded goal in the 79th minute of the game. Just as the ball left her head, the horizontal component of its acceleration was 225 m/s , and the vertical component of its acceleration was -200 m/s (assuming thepositive direction points up). If the ball has a mass of 425 g, what was the magnitude and direction of theforce she applied to the ball? Note- you can ignore the weight of the ball.

Professional Application Consider the following question: A car moving at 10 m/s crashes into a tree and stops in 0.26 s. Calculate the force the seatbelt exerts on a passenger in the car to bring him to a halt. The mass of the passenger is 70 kg. Would the answer to this question be different if the car with the 70-kg passenger had collided with a car that has a mass equal to and is traveling in the opposite direction and at the same speed? Explain your answer.
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…
