A worker drives a 0.500 kg spike into a rail tie with a 2.50 kg sledgehammer. The hammer hits the spike with a speed of 65.0 m/s. If one-third of the hammer’s kinetic energy is converted to internal energy of the hammer and the spike, how much does the total internal energy increase?
A PHYS 1510 student was working on a robotics project. The joints on the machine they were building were powered
by pistons.
Based on how hot the machine was getting, the student was able to figure out that 2.34 J of thermal energy was
produced by every piston every time the piston was fully extended to 0.4064 m.
What was the force of friction that the piston experienced during every extension?
Assume friction is the only source of thermal energy. Include units in Sl.
The food calorie, equal to 4186 JJ, is a measure of how much energy is released when food is metabolized by the body. A certain brand of fruit-and-cereal bar contains 145 food calories per bar.
A.
If a 71.0 kgkg hiker eats one of these bars, how high a mountain must he climb to "work off" the calories, assuming that all the food energy goes only into increasing gravitational potential energy?
Express your answer in meters. H=____________m
B.
If, as is typical, only 25.0 %% of the food calories go into mechanical energy, what would be the answer to part A? (Note: In this and all other problems, we are assuming that 100%% of the food calories that are eaten are absorbed and used by the body. This is actually not true. A person's "metabolic efficiency" is the percentage of calories eaten that are actually used; the rest are eliminated by the body. Metabolic efficiency varies considerably from person to person.)
Express your answer in meters.
H=______________m
