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?

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?

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

Two blocks with different mass are attached to either end of a light rope that passes over a light, frictionless pulley that is suspended from the ceiling. The masses are released from rest, and the more massive one starts to descend. After this block has descended a distance 1.40 m , its speed is 3.00 m/s. If the total mass of the two blocks is 18.0 kg, what is the mass of the more massive block? Take free fall acceleration to be 9.80 m/s2.
Vmax In a laboratory experiment, a sphere of diameter 8.0 mm is released from rest at t = 0 at the surface of honey in a jar, and the sphere's downward speed v when it travels in the honey is found to be given by v = Vmax (1 - e-t/T), where 0.040 m/s and T = 0.50 s. (a) Obtain an expression for a(t). (b) Draw graphs for v(t) and a(t) for the time interval 0 to 2.0 s. (c) Obtain an expression for x(t), choosing the positive x axis as downward, and draw the graph for this func- tion.
