Check Your Understanding The soccer player stops after completing the play described above, but now notices that the ball is in position to be stolen. If she now experiences a force of 126 N attempts to steal the ball, which is 2.00 m away from her, how long will it take her to get to the ball?
The same rocket sled drawn is deceleratedat a rate of 196 m/s2. What force is necessary to producethis deceleration? Assume that the rockets are off. The massof the system is 2100 kg.
Identical twins, each with mass 55.0 kg, are on ice skates andat rest on a frozen lake, which may be taken as frictionless.Twin A is carrying a backpack of mass 12.0 kg. She throws ithorizontally at 3.00 m/s to Twin B. Neglecting any gravityeffects, what are the subsequent speeds of Twin A and Twin B?
A 63 kg astronaut drifting with 7.0 m/s to the right with respect to a spacecraft uses a jetpack to slow down. If ittakes 14.0 s to come to a stop with respect to thespacecraft, what is the force exerted by the jetpack?
After falling from rest from a height of 30.0 m, a 0.500-kgball rebounds upward, reaching a height of 20.0 m. If the contactbetween ball and ground lasted 2.00 ms, what average forcewas exerted on the ball?
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).
As a fish jumps vertically out of the water, assume thatonly two significant forces act on it: an upward force F exertedby the tail fin and the downward force due to gravity. A recordChinook salmon has a length of 1.50 m and a mass of 61.0 kg.If this fish is moving upward at 3.00 m/s as its head first breaksthe surface and has an upward speed of 6.00 m/s after twothirdsof its length has left the surface, assume constant accelerationand determine (a) the salmon’s acceleration and (b)the magnitude of the force F during this interval.
