Experimental tests have shown that bone will rupture if it is subjected to a force density of 1.03 x 10° N/m². Suppose a 70.0-kg person carelessly rollerskates into an overhead metal beam that hits his forehead and completely stops his forward motion. If the area of contact with the person's forehead is 1.5 cm?, what is the greatest speed with which he can hit the wall without breaking any bone if his head is in contact with the beam for 10.0 ms?

1. A hose sprays water into a train car. The hose is fixed in place and directed along the tracks, and the train car can move along the tracks without friction. The hose sprays water at a fixed rate a ([a] =MT-1) and speed v; the mass of the empty car is M. If the train car starts empty and at rest at t = 0, what is its speed at time t?

From 1946 through 1958, Col. John Stapp headed the U.S. Air Force Aero Medical Laboratory's studies of the human body's ability to tolerate high accelerations during plane crashes. Conventional wisdom at the time indicated that a plane's negative acceleration should not exceed 180 m/s2 (18 times gravitational acceleration, or 18g). Stapp and his colleagues built a 700-kg "Gee Whiz" rocket sled, track, and stopping pistons to measure human tolerance to high acceleration. Starting in June 1949, Stapp and other live subjects rode the sled. In one of Stapp's rides, the sled started at rest and 360 m later was traveling at speed 67 m/s when its braking system was applied, stopping the sled in 6.0 m. He had demonstrated that 18g was not a limit for human deceleration. Find the time interval for Stapp and his sled to stop as their speed decreased from 67 m/s to zero.

A bucket that has a mass of 30 kg when filled with sand needs to be lifted to the top of a 25 meter tall building. You have a rope that has a mass of 0.1 kg/m that must be secured to the bucket. It takes 1 meter of rope to secure the bucket. Once the bucket reaches the top of the building it only has mass 24 kg because there was a hole in the bottom and sand was leaking out at a constant rate while it was being lifted to the top of the building.Find the work done lifting the bucket (sand and rope) to the top of the building.

1. The 10-lb block has a speed of 4 ft/s when the force of F = (8t?) Ib is applied. Determine the velocity of the block when it moves s = 20 ft. The coefficient of kinetic friction at the surface is Uz = 0.15. Note: It's okay to use an online equation solver to calculate a number in this problem! v = 4 ft/s F = (8f) lb

The answer I have is 0 kg m/s, not 24 kg m/s. I was just not sure how to calculate to get 0 kh m/s. Can you recheck the problem to see if it was done correctly? Thanks.
