Question

can you help me with letter c? with acceleration being 10.07 m/s2

A wily coyote (Wile E. Coyote, WEC) ties himself to a rocket with an acceleration 10.07 WEC and the rocket are initially at rest. A roadrunner (RR) comes around a curve to the left, then passes WEC at x = 0 with an initial speed of 20 mi/hr to the right. At this instant WEC lights the fuse, which takes ACME eo k an additional five seconds to burn down before the For constant acceleration: rocket ignites. During this initial delay RR does not accelerate. When the rocket ignites and WEC begins to accelerate at time t = 0, RR also begins to accelerate with arR. 1 x = xo + vot +,at² v + vo t a) What is RR's position when the rocket ignites, five seconds after RR passes WEC at x = 0? Report your answer to one digit after the decimal point. = xo + 2 v = v, + at b) The rocket burns out 4.5 s after ignition. What are WEC's position and velocity at this time? Report both answers to one digit after the decimal point. v² = vo² + 2a(x – x,) c) After rocket burnout, WEC continues at constant velocity. How much additional time At has elapsed when WEC reaches the final position 150 yards from the starting position? Report your answer to three digits after the decimal point. d) What value must RR's acceleration arr have so that RR and WEC reach the final position at the same time? Report your answer to two digits after the decimal point. e) What are RR's and WEC's velocities at the final position? Report both answers to one digit after the decimal point.
