- 1.) A car that weighs 4000 Ibs. (1814 kg), crashes into a wall. What is the impulsive force (F) if the car goes from 55 mph (88.5 km/h - 24.6 m/s) to 0 m/s in 0.3 sec? Force Units 2.) What if the same car, traveling at the same speed as before, had "crumple zones" (longer time to stop). When this car hits the wall, it takes 0.75 seconds to come to a rest. What is the new impulsive force (F) on the driver? Force - Units 3.) In a car collision, the driver's body must change speed from a high value to zero. This is true whether or not an airbag is used. How does an airbag reduce injuries? 4.) A baseball is pitched at 35 m/s is hit by a batter. After leaving the bat, the ball has a velocity of 50 m/s. The ball weighs 0.15 kg. The time elapsed during the collision was 0.0015 seconds. What was the force (F) exerted on the baseball? Hint: Watch your signs of the velocities, the direction changes. Force = UnitsKara Moore was applying make up in the parking lot Unaware that Lisa's car was stopped in her lane 30 ft ahead. Kara rear ended Lisa's car. Kara's 1300 kg car was moving a 11m/s and completerly stopped after hitting Lisa;s car in 0.14 sec. What is the magnitude of the force experienced by Kara's car?A high-speed photograph of a club hitting a golf ball is shown in the figure below. Ted Kinsman/Photo Researchers, Inc. The club was in contact with a ball, initially at rest, for about 0.0050 s. If the ball has a mass of 55 g and leaves the head of the club with a speed of 2.3 x 10² ft/s, find the average force (in kN) exerted on the ball by the club. KN
- 1.A 0.726-kg rope 2.00 meters long lies on a floor. You grasp one end of the rope and begin lifting it upward with a constant speed of 0.710 m/s. Find the position and velocity of the rope’scenter of mass from the time you begin lifting the rope to the time the last piece of rope lifts off the floor. Plot your results.(Assume the rope occupies negligible volume directly below the point where it is being lifted.)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.7 What force is required to slow a 1450-kg car traveling 115 km/h to 45.0 km/h within 3.00 s? How far does the car travel during its deceleration? -11600 N -10600 N -10500 N -11500 N
- In a game of baseball, a 1.0-kg ball is pitched to Sarah at 20 m/s. She hits the ball back to the pitcher at the same speed.

- Alice who has a mass of 55.0 KG is riding at 25.0 m/s in her new sports car. when she must certainly slam on the brakes to avoid hitting a cow crossing the road she strikes the airbag that brings her body to stop in 0.6 seconds what average force does a seatbelt exert on her1.50 kg cart 1.50 kg cart 1.50 kg cart 0.30 kg cart 1.50 kg cart 1.50 kg cart 0.30 kg cart 1.50 kg cart 1.50 kg cart Three carts all sit along a level track. A 10-N force is applied to the red cart on the left (Cart 1) for 1 s. After the force has subsided, Cart 1 collides with the blue cart in the middle (Cart 2), that is initially moving leftward at 9 m/s leftward. After the collision, Cart 2 continues forward until it collides with the red cart on the right (Cart 3) completely inelastically.7. Consider the figure below. If the 100 kg block takes 5.5 s to reach the floor after being released from rest, what is the mass m of the block on the left? 100 kg 1.0 m
