Can you help me? I would appreciate if you do. Thank you so muchWe want to find the coefficient of restitution e between the ball and the floor. We will be able to measure the time of flight between subsequent bounces, but not the velocities before and after each impact. Question 1 a. Using the kinematics equation for position, find a relationship between the time of flight tn and the velocity of the ball after the nth bounce. You should obtain a quadratic equation that has two solutions for the time tm, but only one of them represents the time of flight. b. Using the kinematics equation for velocity and the relationship determined in the previous step, find the relationship between the velocity right after the nth bounce and the velocity right before the (n +1)th bounce? c. Given your answers to the previous parts of this question and the definition of €, find the coefficient of restitution e in terms of the subsequent times of flight tn and tr+1.E (2) Pars ats to the other side c) Calculate the otter's velocity, relative to the bank from where it started. viszsub ain biz silto ortof 5 67 18010 Your flight to your friend's house in Halifax has a short layover in Toronto.

- Page The heights of a rock after t seconds, when propelled straight up with an initial speed of 80 feet per second from an initial height of 20 feet, can be modeled by the function s(t) = -16t² + 80t +20. When will the height of the rock be 50 feet? Round your answer to the nearest tenth of a second. CQuestion 3 The position F of a particle moving in an xy plane is given by: F =(2.00t – 5.00t)i +(6.00–700*)} with F in meters and t in seconds.
