A speedboat moving at 30.0 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant acceleration of –3.50 m/s² by reducing the throttle. (a) How long does it take the boat to reach the buoy? (b) What is the velocity of the boat when it reaches the buoy?

How long would the stunt last? How many buses can he clear if the top of the take-off ramp is at the same height as the bus, 3.00 m, and the buses are 6.15 m long?
While driving down a straight road at 70.5 km/h, you pass your physics professor who happens to be out for a jog. He's running at a constant 4.00 m/s, and you decide to slow down and talk physics with him. If you apply your brakes exactly when you pass him on the road, and your car accelerates at 3.58 m/s2 during the breaking, how far do you end up going before he catches up to you?
A soccer player kicks a rock horizontally off a 40.0-m-high cliff into a pool of water. If the player hears the sound of the splash 3.00 s later, what was the initial speed given to the rock? Assume the speed of sound in air is 343 m/s.
Give an example in which velocity is zero yet acceleration is not.
Plus and minus signs are used in one-dimensional motion to indicate direction. What is the sign of an acceleration that reduces the magnitude of a negative velocity? Of a positive velocity?
Two ducks, Donald and Cassiopeia, are gliding gracefully toward eachother along a pond, in a straight line. Donald is initially moving at v =0.500 m/s, and begins accelerating at 0.100 m/s2 at t = 0 s. Cassiopeiamoves at a constant speed of v = 0.700 m/s. If they are initially separatedby 25.0 m, where will they collide? Take Donald’s initial position as theorigin. How long will it take for them to collide?
In a scene in an action movie, a stuntman jumps from the top of one building to the top of another building 4.00 m away. After a running start, he leaps at an angle of 15.0o with respect to the flat roof while traveling at a speed of 5.00 m/s. Will he make it to the other roof, which is 2.50 m shorter than the building he jumps from?
Daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a 42.00º ramp leaning on the leftmost bus, revving at a speed of 34.99m/s. How long would the stunt last? How many buses can he clear if the top of the takeoff ramp is at the same height as the bus, 3.00m, and the buses are 9.59m long? Use 2 decimals and the value of gravity must be 9.81m/s squared
In 1865, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220-m-long cannon with final speed of 10.97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during their launch? (A human can stand an acceleration of 15g for a short time.)
