Coasting due West on your bicycle at 9.6 m/s, you encounter a sandy patch of road 6.7m across. When you leave the sandy patch your speed has been reduced by 3.8m/s to 5.8 m/s. Assuming the sand causes a constant acceleration, what was the bicycle’s acceleration in the sandy patch? Give both the magnitude and direction. How long did it take to cross the sandy patch? Suppose you enter the sandy patch with a speed of only 7.6 m/s. Is your final speed in this case 3.4m/s, more than 3.4m/s, or less than 3.4 m/s? Explain.

A student begins at rest and then walks north at a speed of v1 = 0.55 m/s. The student then turns south and walks at a speed of v2 = 0.53 m/s. Take north to be the positive direction. If the student travels in the stated directions for 30.0 seconds at speed v1 and for 20.0 seconds at speed v2, what is the net displacement, in meters, during the trip? If it takes the student 5.0 s to reach the speed v1 from rest, what is the magnitude of the student’s average acceleration, in meters per second squared, during that time?

A jet plane comes in for a landing with a speed of 120 m/s. The length of the runway is 500 m. From the instant the plane touches the runway, what is the magnitude of the acceleration needed to stop within the runway? Write your answer in terms of m/s2.
Chris stands on top of a giant rock outcrop, 250 feet above the ground.Chris throws a grapefruit upwards, into the air, with initial velocity of 50 feet per second. The grapefruit has a trajectory such that it will fall all the way to the ground. Use calculus to write the equation of the displacement (position) of the grapefruit as a function of time using initial position s = 250 and ground level as position s = 0. Use acceleration a = -32 feet per second per second
A man in a glider leaped off a cliff with an initial velocity of 3.45 m/s. He landed on the ground below, 450 meters away from the cliff. What was the amount of time required for the glider to land on the ground below? How high is the cliff in meters?
Yesterday you walked 20 meters to the right from your house to the bus stop, which took you 20 seconds. You waited at the bus stop for 1 minute before realizing you forgot your Mathematics homework at home. You ran back to your house in 5 seconds. It took you 10 seconds to find your homework, and then you ran back to the bus stop in 5 seconds just in time to catch the bus. What was your average velocity for the entire period of motion?

A scooter begins at rest at t0 = 0 seconds. The scooter starts moving, and eventually covers a distance d = 727 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the scooter's motion is in the northern direction A: What was the scooter's displacement in the northern direction during this period, in meters? B: What was the scooter's average velocity in in the northern direction vavg,N, in this period in meters per second? C: If the scooter's final velocity at tf was 12 m/s, what was the scooter's average acceleration in the northern direction, aavg,N, during this period in m/s2?
