A group of Loyola students decided to depart from Earth after graduation to find work on Mars. Before building a shuttle, they conducted careful calculations. A model for the velocity of the shuttle, from liftoff at t = 0 s until the solid rocket boosters were jettisoned at t = 84.8 s, is given by ?(?)=0.001111333?^3−0.085745?^2+30.69?+9.71 (in feet per second). Using this model, estimate the global maximum value =?and global minimum value =?
On Mars, a ball is rolling from a ground to a hill, and we know the height of the hill, Z, is 10 m, and the initial velocity ofthe ball on the ground and the final velocity on the hill are known: V1 = 20 m/s and V2 = 10 m/s, respectively. The mass ofthe ball, m, is 4 kg. The gravitational acceleration on Mars, gMars, is 3.7 m/s2. Please calculate 1) the change in kineticenergy, ΔKE, in J and 2) the change in potential energy, ΔPE, in J, of the ball for the rolling process.
