A rock is thrown directly up with an initial velocity of Voy = 21.3m/s at instant A as shown in the figure below. As it moves up it will reach a certain heighth = 13.4m at an instant B. It come back to the same height during it's fall from the maximum height at instant C. Determine the time it takes for the rock to go fromB to C. Express your answer using one decimal place in units of seconds and take g = 9.81m/s².Answer:A

Basic kinematics variables using calculus: The velocity of an object is given by the expression v(t) = 3.00 m/s + (4.00 m/s3)t2, where t is in seconds. Determine the position of the object as a function of time if it is located at x = 1.00 m at time t = 0.000 s.

A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average velocity in in the northern direction vavg,N, in this period in meters per second? 2. If the motorcycle's final velocity at tf was 12 m/s, what was the motorcycle's average acceleration in the northern direction, aavg,N, during this period in m/s2?

In an experiment, a shearwater (a seabird) was taken from its nest, flown a distance 5120 km away, and released. It found its way back to its nest 12.5 days after release. Part A If we place the origin in the nest and extend the +x-axis to the release point, what was the bird's average velocity for the return flight? Express your answer in meters per second. ANSWER: Vay.-x = m/s Part B What was the bird's average velocity for the whole episode, from leaving the nest to returning? Express your answer in meters per second. ANSWER: Vav. = m/s

The Beretta Model 92S (the standard-issue U.S. army pistol) has a barrel 127 mmmm long. The bullets leave this barrel with a muzzle velocity of 349 m/sm/s. 1) What is the acceleration of the bullet while it is in the barrel, assuming it to be constant? Express your answer in meters per second squared. 2) What is the acceleration of the bullet while it is in the barrel, assuming it to be constant? Express your answer as a multiple of acceleration due to gravity g. 3) For how long is the bullet in the barrel? Express your answer in seconds.
