An airplane flies horizontally at constant speed in a straightline direction. its state of motion is unchanging. in other words, it is in equilibrium. two horizontal forces act on the plane. one is the thrust of the propeller that pulls it forward. the other is the force of air resistance (air friction) that acts in the opposite direction. which force is greater?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
