Please answer 5 and 11 thank you

11) Kris is driving her VW beetle at 25 m/s, while an ((C ambulance drives at 36 m/s directly in front of her. Assume the speed of sound is 344 m/s. If the ambulance emits sound at 2 kHz, what is the frequency that Kris detects listening to the siren?5) A test rocket starting from rest at point A is launched by accelerating it along a 200m gravity incline at 1.90 m/s2. The incline rises at 350 above the horizontal, and at the moment 1.90 m/s the rocket reaches the end of the ramp the 200.0 m engine is turned off, so that the rocket is subject to gravity as the only force. a) What is the speed of the rocket at the end 35.00 of the ramp?
