Non ENE CNBC During a test a rocket travels upward at 75 s, and when it is 40 m from the ground its engine fails. Determine the maximum height sp reached by the rocket and its speed just before it hits the ground. While in motion the rocket is subjected to a constant downward acceleration of 9.81 m/s² due to gravity. Neglect the effect of air resistance. 1. The man pushes on the 60th crate with a force of F-63.60h. The force is always directe down at 30" from the horizontal. If the magnitude of F is increased until the crate begins t slide, determine the crates initial acceleration if the coefficient of friction is p-0.3. 67 6lb
