A rocket starts from rest and moves upward from the surface of the earth. For the first 7.9 seconds of its motion, the vertical acceleration of the rocket is given by a = (3.5m/sec). (a) What is the height of the rocket above the surface of the earth at 1 = 7.9 seconds? 7.96 27.65m (b) What is the speed of the rocket when it is 92.5 m above the surface of the earth?

Problem 2.51 Constants| Periodic Table Part A During the complicated sequence that landed the rover Curiosity on Mars in 2012, the spacecraft reached an altitude of 142 m above the Martian surface, moving vertically downward at 32.0 m/s. It then entered a so- called constant deceleration (CD) phase, during which its velocity decreased steadily to 0.75 m/s while it dropped to an altitude of 23 m What was the magnitude of the spacecrafts acceleration during this CD phase? Express your...
