8. The great white shark can have a mass as great as 3100 kg. Suppose such a shark is cruising the ocean when it spots a meal: a 210 kg fish heading east at 8.60 m/s. The shark rushes north at 3.40 m/s and swallows the prey at once. At what angle 0 with respect to the east direction will the shark be moving immediately after the snack? degrees

2 trucks are driving an icy road and coming towards a 4way perpendicular intersection and driver A is driving a 3100 kg truck north-ward at 22m/s while driver B goes eastward in a 1100kg truck, they crash and stick together travelin at 59◦ north of East. What is Car B's original speed?
Question 9 (5 points) A 1120 kg car with no air bag collides with a railing traveling 21.9 m/s. The 62.5 kg driver, who is not wearing a seat belt, slams into the steering wheel and is contact with it for 0.0500 s. What magnitude of force does the driver experience as a result of the collision? Imagine that the crashed car deployed an air bag during the impact. The driver was in contact with the air bag for 0.500 s during the crash. What magnitude of force does the driver experience as a result of the collision? N Blank 1: Blank 2:
On the set of a new Hollywood movie, a 74.1-kg stunt actor (Max Payne) is tossed straight out of a helicopter hovering (stationary) at a height of 43.4 meters. The stunt actor is thrown from the helicopter at a speed of 4.17 m/s, eventually landing in the water below. Determine the stunt actor's impact speed and assume negligible air resistance. You can use the approximation that g = 10 m/s2.
1. For the purposes of this problem make sure you remember that the positive x direction is to the right. A 0.500 kg crash cart was rolling to the left at &; = -1.00 m/s. It was hit with a rubber hammer. Just afterwards the cart was rolling to the right with Uf = +2.50 m/s. The hammer was in contact with the cart for only 5.00 milliseconds. Remember to specify the direction in your answers as either postive or negative. (a) What is the change in momentum, Ap, for the cart? (b) What is the Impulse, I, applied by the hammer to the cart? (c) What is the average force, F, applied by the hammer to the cart? +x X+ Vf +X
9. A 1200 kg car drives at an initial velocity vo = 45 m/s along a highway. At t = 0, the driver releases the gas, and the car slows to a stop due to a drag force given by Fdrag = -b v, where b = 15 kg/s³. Derive a function for the car's velocity as a function of time and solve it for the car's velocity at 10, 20, and 30 s.
2. A villain with mass 65.0 kg runs at a velocity of 9.26 m/s directly into Chuck Norris' fist moving at a speed of 0.150 m/s. The villain is knocked back at a velocity of 8.52 m/s and angle 20.0° from the horizontal, while Chuck Norris' fist moves at a velocity of 0.0745 m/s and 10.0° from the horizontal. a.

7. A 730-N man stands in the center of a frozen pond of radius 5.00-m. There is no friction between the man's shoes and the ice, preventing him from walking off of the pond. The man then picks up a 1.20-kg rock lying beside him and throws it horizontally at a speed of 5.00-m/s. How long does it take the man to reach the edge of the pond? Answer: 61.7 s

An open train car, with a mass of 2050 kg, coasts along a horizontal track at the speed 2.792.79 m/s. The car passes under a loading chute and, as it does so, gravel falls vertically into it for 2.792.79 s at the rate of 475 kg/s. What is the car's speed vf after the loading is completed? Ignore rolling friction.
3. You are the design engineer in charge of the crashworthiness of new automobile models. Cars are tested by smashing them into fixed, massive barriers at 45.0 km/h to the left. A new model of mass 1500 kg takes 0.150 s from the time of impact until it is brought to rest. Calculate the average force (magnitude and direction) that is exerted on the car by the barrier?
Squids rely on jet propulsion to move around. A 1.50 kg (including the mass of the water inside the squid) squid drifting at 0.40 m/s suddenly ejects 0.10 kg of water to get itself moving at 2.50 m/s. If drag is ignored over the small interval of time needed to expel the water (why can we do this?), what is the water’s ejection speed relative to the squid? Include sketch
