I WILL RATE HIHG IF YOU ANSWER ALL POINTS PLEASE *13

1. The solution to Part 1 should have looked like this. (a) a = Consider the sketch below. Adjust the colored sliders so that the corresponding vo, v, and a vectors are oriented in the correct directions. t = Top of cliff S Yo ✔m/s ✔m/s² Y VO a Bottom of cliff Y It takes 2.96 s for a rock to hit the ground when it is thrown straight up from a cliff with an initial velocity of 7.00 m/s. Assume all values are correct upto 3 significant figures. Vo V Using the notation Ay=y-y for displacement, y for position after time t, yo for the initial position, v for velocity after time t, vo for initial velocity, and a for acceleration, determine what quantities are known and what are unknown. • Enter the values of some known quantities below. • Make sure you account for the signs of the vectors using the coordinate system used in Part 1. Enter to 3 significant figures Vo= x a

Something to think about: Do you need to split the trip into two parts: 1. the rock's journey up, and 2. the rock's journey down? Is it possible to solve without splitting the motion into two parts? Ay = vt (vo + v) 2 v=v₁ + at ²= √²+2aAy Ay=v₁t+1=1/1at² Ay= Ду - t (c) Calculate the height of the cliff. Note: The height of the cliff should be a positive value. Enter to 3 significant figures h= ✔m (d) How long would it take the rock to reach the ground if it is thrown straight down with the same speed instead of up? Enter to 3 significant figures t = ✔S Sense-making: Check if the answer in part (d) is less than the time in part (a).
