Kicking the ball a. In the gravity only case what is characteristic about the x velocity?...
Homework Answers
a)
velocity of ball along y axis changes because a constant acceleration (acceleration due to gravity) acts on the object, which changes its velocity at every instant
but for x axis, velocity along x axis remains constant throughout its flight
====
b)
since there is air resistance presence, noe its velocity aling x axis changes too, in other words its horizontal and vertical velocity decreases simultaneously.

If a ball rolls off the edge of a table at velocity u, what happens to its angular velocity ? Say if I wanted to calculate the velocity of the ball as it strikes the ground using energy methods, would I use PEi + KEi = PEf + KEf and I plug in u for the initial kinetic (1/2mu^2), mgh for initial potential, then 1/2mv^2 + 1/2 I*w^2 for the final kinetic ? And then solve for v ? Or...

10.7 A soccer player deflects a soccer ball by kicking it. Initially the soccer ball (mass 0.40 kg) is moving horizontally to the left witha speed of 20.0 m/s. The kick causes it to have an initial, post-kick velocity of 30.0 m/s with an angle of 45 upward and to the right. If the time that the player's foot is in contact with the soccer ball is 0.010 seconds find: A. The impulse of the net force The average net...

The acceleration of gravity is found by dropping a ball from various heights. The data for the experiment is as follows: Distance, d (meters): 15.43 17.37 19.62 21.68 Time, t (seconds): 1.804 1.915 2.043 2.149 a.) Copy these data and add a third row which contains the calculated accelerations due to gravity as given by g = 2d/t^2. b.) By finding the mean and standard deviation, show that the answer is inconsistent with the accepted value of g = 9.80...
