Hi can you please help me with these problems. please show workouts so I can understand. Thanks

IS. A student is asked to determine tlte work done on a block of wood when the block is pulled horizontally using an attached string The student is supplied with a spring scale, a stopwatch, and a meterstickr Which of the following graphical analysis techniques will allow the student to determine tlte work done an die block by the string? (A) Graphing the force as a function of time and calculating the slope (B) Graphing the force as a flutction of time and calculating the area under the curve [(3) Graphing the force as a [traction of distance and calculating the slope 1D) Graphing the force as a function of distance and calculating the area under the curve AP Physics] Pages ME- in we Energy Practice 2022 Refer to the following material for answering group of questions. F A crate is on a horizontal frictionless surface. A force of magnitude F is exerted on the crate at an angle 6 to the horizontal, as shown in the figure above, cursing the crate to slide to the right. The surface exerts a normal force of magnitude Even the crate. As the crate slides a distance d, it gains an amount ofkinetic energy AK. While Fis kept constant, the angle 9 is now doubled but is still lass than 90. Assume lhe crate remains in contact with the surface. 14 As the crate slides a distance d, how does the new gain in kinetic energy compare to AK? (A) The new gain is greater than M. (B) The new gain is less than AK [(3) The new gain is equal to AK. ID) The new gain is greater or less than AK depending on the value of 9 IS. F -- A force F is exerted on a 5 kg block to move it across a rough surface, as shown above. The magnitude ofthe force is initially 5 N, and the block moves at a constant velocity. While the block is moving. the force is instantaneously increased to 12 N. How much kinetic energy does the block new gain as it moves a distance of2 In? (A) 101 on 141 (C) 241 in) 341 16.
