1.An object is thrown upward at a speed of 178 feet per second by a machine from a height of 7 feet off the ground. The heighthof the object aftert

seconds can be found using the equationh=16t^2+178t+7

When will the height be 262 feet?

when will the object reach the ground?

2.We know that objects in freefall follow the equation for heighth, in meters,h=4.9t^2+c, wheretis time in seconds, andcis the initial height. A student timed the drop at 1.43 seconds.

Use this to determine the height from which the ball was dropped, to at least 2 decimal places.
