a soccer ball kicked at an angle 60 degrees with respect to the floor and after two seconds landed 10 meters ahead Calculate the average velocity in x the initial velocity and y the initial velocity and the maximum height​

All the simple machines make work easier to do by changing the or of a force. a. size; type b. work; type c. size; direction d. type; direction

What object a collides with object b and bounces back its final momentum is?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
