[1.23] Calculate the force necessary to accelerate a 20,000-Ibm rocket vertically upward at a rate of 100 ft/sec². Assume g = 32.2 ft/sec².

(b) An electric motor lifts a mass of 500 kg from the ground to a height of 30 m in 1.5 minutes. Calculate the motor's output power during operation. The gravitational acceleration, g, is 9.81 m. s-².

Two box hang from the ends of a string suspended from a frictionless pulley. The mass on the left is chosen to create a tension of 4 N in the string. The box on the right has a weight of 2 N. What will be the acceleration of the box on the right? Assume the acceleration of gravity is 9.8 m/s?. 4 N 2 N

4. Please provide full body diagram with explanation

A 2.0 kg object is moving to the right with a speed of 1.0 m/s when it experiences the force shown in the graph at right. What are the object’s speed and direction after the force ends? Paste the completed Bar Chart below. 1. identify the system 2. draw a quick sketch of the initial state of the object(s) 3. do a momentum bar chart

Block 1 (19 kg) is setting on the floor of an elevator. A rope pulls vertically up on block 1 with a tension of 10 N. The elevator is moving downward with a decreasing speed and the magnitude of the acceleration is 2 m/s2.On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram, enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component.
