- 3. An elevator is moving downward at 1m/s. It is speeding up, with an acceleration of 3m/s². A block with a weight of 40N sits inside the elevator. a) What direction does the acceleration point? b) What is the mass of the block? c) Draw a force diagram of the block, and fill out the force table for the block below. (There are no horizontal forces so we don't need the x column.) Force d) Solve for any unknown forces on the block. y +y 1m/sFor the following problem, draw free-body diagrams and solve for the requested unknown. Use g = 9.8 m/s/s. A 22.6-N horizontal force is applied to a 0.0710-kg hockey puck to accelerate it across the ice from an initial rest position. Ignore friction and determine the final speed (in m/s) of the puck after being pushed for a time of .0721 seconds. PSYWPlease write legibly.
- 1. Describe what you saw in the context of Newtons third law (equal and opposite forces): For every action, there is an equal and opposite reaction. Be careful here - where does the force of thrust come from? a. Which direction does the force of thrust point? Draw a free-body-diagram. Check that this makes sense given your answer to above.b) A 4 kg block is pulled along a rough inclined plane by a force of 71 N as shown in Figure 2. Given the coefficient of friction between the block and inclined plane is 0.4. i. Draw a free body diagram. ii. Calculate the acceleration of the block. 37⁰ Figure 23. Consider an inclined plane with two balls suspended as shown below. The pulley has negligible mass and both the pulley and the surface of the incline are frictionless.a. If one of your classmates calculated that, once released, the acceleration of the blocks would be 43?, without doing any calculations, say whether or not this could be a reasonable value for the acceleration.b. Draw and label a free body diagram (FBD) for each ball. (Don’t break any forces into components for the FBDs—save that work for the next question. Be sure your drawings show clearly any information you know about the directions and relative magnitudes of the forces.) Rank the relative magnitudes of all forces in your FBDs. (I’m looking for a single ranking that includes every different force in both FBDs, separated by <, >, or =.)Ball A: Ball B:relative sizes of the magnitudes of all forces in FBDs:__________________________________________________________________c. Use the FBDs from the previous…
