B Q1// Using the Work and Energy principles Only, solve the following Question: During a test a rocket travels upward at 75 m/s, and when it is 40 m from the ground its engine fails. Determine the maximum height SB 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/s? due to gravity. Neglect the effect of air resistance. VA= 75 m/st SA=40 m
