Finally, the water park at an amusement park has rides that are essentially this lab on a large scale. A 45 kg rider falls a total distance of 22.5 m for one of these, sliding down an incline of 31.5 degrees. If there were no friction, how long would the ride last (while they are in the tube?) How fast would they exit the tube in m/s?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false

Which of the following is the result of the nuclear weak force? the instability of large nuclei the repelling force between positively charged protons the structure of the atom certain types of nuclear decay

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
