PLEASE HELP!! Questions for problem:

a) Draw a FBD for Calvin and Hobbes for when they are moving up the slope of the jump.

b) Find their net acceleration.

c) If the length of the jump is 7.5m, will they fly three the air? If not, how far up the slope with they make it?

d) Calvin was not satisfied with their results of the last attempt, so he polished the bottom of their sled with some wax to decrease the coefficient of friction by a factor of 2, causing them to reach the bottom jump with a speed of 11 m/s. How far will they fly through the air before landing (assume horizontal surface even with the top of the jump)?

Note : I will award 50 pts and mark brainliest if you give step by step explanation (would prefer if you just upload a picture of work), if you don’t show work and just write a bs answer, i will report and you won’t get any points)

What happens to the light rays when they hit the specimen?

Jason and mia are both running in a race. as they approach the finish line, you being the physicist that you are decide to time how long it takes them to reach the end of the race. when you start your stop watch (you can take this as time t = 0 s) you notice that mia is an unknown distance d ahead of jason and both are moving with the same initial velocity v_0. you also notice that jason is accelerating at a constant rate of a_j, while mia is deaccelerating at a constant rate of -a_m. jason and mia meet each other for the first time at time t = t_1. at this time (t = t_1) jason's velocity is two times that of mia's velocity, meaning v_j (t_1) = 2v_m (t_1). a) draw the position vs. time graph describing mia's and jason's motion from time t = 0 to time t = t_1. clearly label your axes and initial conditions on your graph. b) draw the velocity vs. time graph describing mia and jason's motion from time t = 0s to time t = t_1. clearly label your axes and initial conditions on your graph. c) how long from when the stop watch was started at t = 0s did it take mia and jason to meet? express your answer in terms of know quantities v_0, a_m, and a_j. d) when the stop watch started at time t = 0s, how far apart, d, were mia and jason? express your answer in terms of know quantities v_0, a_m, and a_j.
