Tutorial Exercise If a rock is thrown upward on the planet Mars with a velocity of 16 m/s, its height above the ground (in meters) after t seconds is given by H = 16t - 1.86t. (a) Find thevelocity (in m/s) of the rock after 1 second. (b) Find the velocity (in m/s) of the rock when t = a. (c) When (in seconds) will the rock hit the surface?

A model rocket is fired vertically upward from rest. Its acceleration for the first three seconds is a(t) = 90t, at which time the fuel is exhausted and it becomes a freely "falling" body. Eighteen seconds later, the rocket's parachute opens, and the (downward) velocity slows linearly to -11 ft/s in 5 seconds. The rocket then "floats" to the ground at that rate. (a) Determine the position function s and the velocity function v (for all times t). 4512 if 0 sts 3 405 if 3 26 15r3 if 0 sts 3 405 if 3 26
2. (b) Suppose instead that the true speed of the car as a function of time is described by v(t) = 30√t (still from t = 0 to t = 4). Sketch a graph of the car’s speed vs. time. (c) Since the speed is no longer constant, it is much harder to calculate the distance traveled. But we can still try. Suppose we wanted to just calculate how far the car went in the single minute from 1:00 and 1:01. Let’s pretend that the car’s speed is constant for this single minute. What might be a reasonable approximation for the car’s speed, in this scenario? Under this assumption, approximately how far did the car go during this minute? Represent the distance traveled during this one minute as an area in your diagram from part (b).
A particle has zero velocity initially (i.e., at time t = 0 ) and its acceleration at t seconds is a(t) = 72t - 4t³ meters-per- second per second.
