What can you say about the acceleration of the block

Reference no: EM132520439

Part A. See the procedures below and answer the questions that follows:

Question 1. Describe a situation where the block moves as the force is applied to it, yet the force does no work over a non-zero time interval. How can this be?

Question 2. Set the initial position of the block to zero, and set the initial velocity to -3 m/s. Run the simulation. When is the work negative? When is it positive? Why?

Question 3. Since the force is constant, what can you say about the acceleration of the block?

Question 4. How can you maximize the final velocity of the block? Can you do the same amount of work and have the block moving more slowly?

Question 5. Create a graph to represent the force (y-axis) and the position (x-axis).

Question 6. What is the area under the curve of this graph?

Part B. Given the figure at the right, derive the equation below.

a = ((m₁ - m₂)/(m₁+m₂))g

Part C. Solve the problem below:

An auto accelerates forward from 7.0 m/s at a uniform acceleration of 0.71 m/s². It travels 1.033 km while accelerating.
a. How fast is the auto moving just as it is traveled the 1.033 km?
b. How many seconds did it take to travel the 1.033 km?
