a block mass 70kg is dragged up a frictionless slope for 15cm the slope has an angle of 20 degrees above the horizon without necessarily solving for the work done on the block describe the situation physically tell me what forces are at play and how they act. in what direction? what physic principle will you need? what trigonometric principles will you need and what do these principals mean? Demonstrate your knowledge of work and energy in your description solving problem will help but not full credit

Consider a rope lowering a mass m=2.45kg at a constant speed v=8.73 m/s down a distance of d=5.72 m as shown in the figure below.  c) What is the work done on the mass by the tension in the rope as it descends a distance d=5.72 m? d) What is the change in kinetic energy of the mass as it descends a distance d=5.72 m?

Question 2 Force vs. Position for a Sliding Box 25 20 15 2 10 2 Position (m) - distance from the starting location Which of the following could be true about the line on the graph? Your answer: O The area between the line and the x-axis gives the value of power. O The area between the line and the x-axis gives the value of work. O The slope of the line gives the value of power. O The slope of the line gives the value of work. IN ao

In a popular new mini hockey game, players use small launchers with springs to move a 5 gram puck. Each spring has a spring constant of 150 N/m and can be compressed up to 5 cm. Solve for the maximum speed with which the puck can be launched. Show all of the work necessary to reach your solution. Start with general equations and explain what you are doing and why you did what you did. Evaluate your solution. Describe how you evaluated your answer and whether or not you think your answer is reasonable. I just need help with question #2 please

Please answer and explain the following question. Thank you

A 5.6 kg block is sliding across a surface while experiencing a force of 55 N. The block has a displacement of 7.5 meters to the right.

Conservation of Energy When Work is Done Whiteboard Problems (Page 10):917 \ 1. A 10.0 kg block rests at the top of an incline that is 4.00 m high and 5.00 m long. A) Find the potential energy of the block when it is at the top of the incline. B) What is the speed of the block at the bottom of the incline, if it is frictionless? C) If the incline is not frictionless, and the block experiences a constant 10.0 N force of friction as it moves down the incline, find the speed of the block at the bottom.
