An experiment is performed in which a force is applied to two objects (A and B) and the resulting acceleration is measured. The graph below summarizes the results. Answer the following questions:

a. What is the relationship between force and acceleration?

b. What are the units for the slope of the line? Show you work below:
acceleration (m/s2)
Force (N)

c. Using the line equation (y = mx +b), derive a general equation that describes the relationship between force and
acceleration.

d. What does the equation you derived above tell you about the relationship between mass and acceleration?

Amass m = 74 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius r = 18.4 m and finally a flat straight section at the same height as the center of the loop (18.4 m off the ground). since the mass would not make it around the loop if released from the height of the top of the loop (do you know why? ) it must be released above the top of the loop-the-loop height. (assume the mass never leaves the smooth track at any point on its path.) 1. what is the minimum speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track? 2. what height above the ground must the mass begin to make it around the loop-the-loop? 3. if the mass has just enough speed to make it around the loop without leaving the track, what will its speed be at the bottom of the loop? 4. if the mass has just enough speed to make it around the loop without leaving the track, what is its speed at the final flat level (18.4 m off the ground)? 5. now a spring with spring constant k = 15600 n/m is used on the final flat surface to stop the mass. how far does the spring compress?
