I drop a penny from the top of the wall by the tennis courts and it takes 1.85 seconds to hit the ground. Calculate the velocity in m/s after 1.10 seconds of freefall. (solve for velocity, so use the basic acceleration equation)

A runner competes in a 1500 meter straight-line race. The runner completes the first 650 meters in 4.00 minutes and the following 850 meters in 6.00 minutes. Calculate the average velocity of the runner in km per hour.

You throw an object up with a speed of Voy=1m/s from a height of y=25m. What is the object's final velocity, in meters per second, as it impacts the ground?

Please answer the following question(s): 1. The speed of a boat in still water is vá. A river flows with a speed of v₁. The boat travels distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. vb vb Downstream positive Vr Upstream negative Vr
