A truck moving at 30.0 m/s undergoes a perfectly inelastic head-on collision with a car movingat 22.0 m/s. The total mass of the truck, including the driver is 9000 kg and the total mass of thecar, including the driver and passenger, is 1500 kg. Each driver has a mass of 60.0 kg and thecollision time for the drivers is 0.200 s. The car passenger has a mass of 60.0 kg and is notwearing a seatbelt. The passenger's collision time is 0.010 s. What is the average force on thetruck driver, th e car driver, and the passenger?

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes.t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
