A police investigator arrives at an accident scene where he finds that a gray 1000-kg Honda Civic has collided with a red 2000-kg SUV. From the skid marks, he is able to determine that the Honda was initially travel ing due east when the driver hit the brakes, while the SUV was going due north. After the collision, the Honda skidded 37 east of north (what other angle could it bel) for a distance of 3.5 m, whife the SUV skidded 37 north of east for a distance of 4.0 m. The pre-collision skid marks of the Honda 435 m 37 215 m are 43.5 m Idng and the pre-collision skid marks of the SUV are 21.5 m long, as shown. The coefficient of friction of Honda tires with the pavement is 0.7, while that of the SUV tires is 0.8. Help the investigator work out the initial speeds of the two vehicles before they hit their brakes. a) From the lengths of the skid marks after the collision, find the speeds of cach vehide just after the collision. b) Use conservation of momentum during the collision to find the speed of each vehicle just before the collision. (Hint: Remember that momentum is a vector.] ) From the lengths of the skid marks before the collision, determine the initial speeds of the two vehicles before they hit their brakes

Squids are the fastest marine invertebrates, using a powerful set of muscles to take in and then eject water in a form of jet propulsion that can propel them to speeds of over 11.5 m/s. Wwhat speed (in m/s) would a stationary 1.90 kg squid achieve by ejecting 0.115 kg of water (not included in the squid's mass) at 3.50 m/s? Neglect other forces, including the drag force on the squid. HINT m/s
stretch 38. Realizing that he could not drive up a 30°, ice-covered hill because there was no friction, Sir Isaac Newton had stopped his cart, of total mass 500 kg, at the bottom. He was struck in the rear by a London stage coach, of total mass 1500 kg. trav- elling at 20 m/s. The two vehicles stuck together, with nothing breaking loose, and slid up the hill in a straight line. How far up the slope did the wreckage get before coming to rest? (SIN '70)

The 75.0 kg swimmer dives horizantally off a 465 kg raft initially at rest. If the diver's speed immediatley after leaving the raft is 5.00 m/s. What is the magnitude of the corresponding raft speed?
An acrobatic buccaneer swings from one rope to another in the rigging of a pirate ship. As she grasps the rope, her mass is m, 63.5 kg; knots on the rope make the rope's effective mass m, 1.50 kg. From the height %D she grabs the rope, she swings up a further distance of 1.50 m. Assuming that her collision with the rope is perfectly inelastic, answer the following questions: {Note: Treat as a ballistic pendulum problem!} mehanical a) Does the buccaneer's collision with the rope conserve her-kietie en- ergy? {Y/N?} b) Neglecting any energy losses due to friction, air drag, etc., determine the velocity of the buccaneer + rope system right after she grabs the rope in m/s. {Assume a closed system, thus Conservation of Energy} c) Is it possible to calculate the buccaneer's initial speed before she grabbed the rope from the information given? {Y/N?}
A tennis player receives a shot with the ball (m = 0.060 kg) travelling horizontally at 50.0 m/s and returns the shot with the ball travelling horizontally at 40.o m/s. If the racquet was in contact with the ball for 0.015 seconds, find the force of the racquet on the ball.

Antiballistic missiles (ABMs) are designed to have very large accelerations so that they may intercept fast-moving incoming missiles in the short time available. What is the takeoff acceleration (in m/s2) of a 10,000 kg ABM that expels 225 kg of gas per second at an exhaust velocity of 2.65 ✕ 103 m/s? (Enter the magnitude.)

Daredevil Darla has heard that to avoid injury when jumping out of her rocket she should bend her knees upon landing. Darla has a mass of 74 kg. If just before contact with the ground, she has a downward speed of 7.3 m/s, then. . . (a) In a stiff -legged landing she comes to a halt in 2.0 ms. Find the average net force that acts on her during this time. ( b) When she bends her knees, Darla comes to a halt in 0.10 s. Find the average net force now. (c) During the landing, there are two forces acting on Darla: the normal force from the ground points upward, while her weight force points downward. The average net force acting on Darla includes both of these forces. Taking into account the directions of the forces, find the force of the ground on Darla in parts (a) and (b).
I would appreciate some hwlp with this question. Thanks! A model rocket consisting of a 61.0-g chassis and a 30.5-g engine is taken on an interstellar mission and fired in outer space. The engine produces 5.00 N of thrust while expending 13.0 g of fuel at a constant rate during a 2.04-s burn. (Assume the mass of the engine includes the mass of the fuel.) (a) What is the average exhaust speed of this rocket's engine? (b) If the rocket starts from rest, what is its final velocity? (Assume the thrust to be in the positive direction. Indicate the direction with the sign of your answer.)
