On the moon, each kilogram of mass is pulled down with 1.6 newtons of weight. Add a dashed line to your graph showing the results if this activity had been done on the moon. How does the slope of the moon line compare to the slope of the earth line? Is it steeper (more vertical) or shallower (more horizontal)? If the activity has been done on Jupiter, the resulting line would have had a steeper (more vertical) slope. What does this tell you about the strength of Jupiter's gravitational field as compared with Earth's?

A23 kg log of wood begins from rest, 300 m up a sluice (a water track used to transport logs, think of it as an inclined plane with negligible friction) inclined at 20° to the horizontal. after it reaches the flat waterway at the bottom it collides elastically with a 100 kg block of wood initially at rest near the base of the incline. (a) how long does it take the 23 kg log to travel down the incline? (b) what is the speed of the 23 kg log at the bottom of the incline? (c) what are the velocities of both blocks of wood after the collision? (d) what is the total kinetic energy before the collision? (e) what is the kinetic energy of the 23 kg log after the collision? (f) what is the kinetic energy of the 100 kg block of wood after the collision? (g) what is the total kinetic energy after the collision? (h) compare the total initial and total final kinetic energies. is this consistent with what you would expect for elastic collisions? explain!

The most important difference between a wedge and an inclined plane is a. their size b. their shape c. how they are used d. what they are made of

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
