A sounding rocket, launched vertically upward with an initial speed of 74.0 m/s, accelerates away from the launch pad at 6.00 m/s. The rocket exhausts its fuel, and its engine shuts down at an altitude of 1.25 km, after which it moves freely under the influence of gravity. (a) How long is the rocket in the air? 47.75 S (b) What is the maximum altitude reached by the rocket? 2.244 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. km (c) What is the velocity of the rocket just before it strikes the ground? magnitude direction 209.749 downward Need Help?
