2. [-/2 Points] An object undergoes uniformly accelerated motion from point x1 = 5 m at time t1 = 3 s to point X; = 44 m at time :2 = 7 s. (The direction of motion of the object does not change.) (a) If the magnitude of the instantaneous velocity at fl is v1 = 2 m/s, what is the instantaneous velocity v2 at time t2? (b) Determine the magnitude of the instantaneous acceleration of the object at time t2. Additional Materials L] Uniformly Accelerated Motion D Appendix 3. [-/10 Points] Use the exact values you enter to make later calculations. Jack and Jill are on two different floors of their high rise office building and looking out of their respective windows. Jack sees a flower pot go past his window ledge and Jill sees the same pot go past her window ledge a little while later. The time between the two observed events was 4.4 s. Assume air resistance is negligible. (a) If the speed of the pot as it passes Jill's window is 65.0 m/s, what was its speed when Jack saw it go by? (b) What is the height between the two window ledges? Additional Materials D Uniformly Accelerated Motion L2 Appendix
