Question

1. If you were to double the mass of the block and cart, what effect would this have on s? 2. If you were to launch a block with m 0.500 kg up a ramp with 0 15o and uk 0.30 with a plunger with k- 200 N/m which compresses by 0.040 m, what distance would you expect it to travel? Show your working below. 3. If you were to place the ramp from Question 2 horizontally and launch the block, what distance would you expect it to travel? Show your working below. 4. Why does the right hand side of Equation 7 not include a term for the final gravitational potential energy of the block if the final position of the block is above the height of the bench?

Equation for question 4: 1/2kx^2+mg*s*sinΘ = μ*mg*s*cosΘ

Q5. Why can the work done by gravity on a hanging mass be ignored? (Hint: the masses return to their original height)
