A boat approaches a two-mile marker 100 m ahead at a velocity of 28.5 m/s. The pilot reduces the throttle, slowing the boat with a constant acceleration of −2.80 m/s2.

How long (in s) does it take the boat to reach the marker?

What is the velocity of the boat when it reaches the buoy?

You throw a ball vertically upward with an initial velocity of 10 m/s from a window located 20 m above the ground. Knowing that the acceleration of the ball is constant and equal to 9.81 m/s^2 downward (this makes for negative acceleration as upward motion is positive and downward motion is negative and gravity pulls downward), determine: (a) The acceleration at t = 2 s (b) The equation for velocity (Because you are looking for an equation for velocity, you...
