To understand how to do this solution, see the very end of this document for a step by step solution. Note, the formula only gives the magnitude of the acceleration, not the direction. How far does the object fall from the start of the d= drop until it hits the ground? How long does this take? t= Use the formula to calculate the acceleration. a= Both calculations of acceleration should be close to the same result and close to the standard value for the acceleration of gravity, 9.8 111/82. Use the range and time data for the red object to calculate the horizontal velocity for the time interval v1= 0.0 s to 0.2 s Calculate the horizontal speed for the time interval of 1.00 s and 1.20 s. (df di) [(5:12) (51:15)] R] ll _' ' ' ' Based on the data recorded, a the dropped object hits the ground before the red object. b both objects hit the ground at the same time. c the fired object hits the ground before the dropped object. 3 Based on the data recorded, the horizontal speed of the red object a slows down as it moves right b is constant 0 speeds up as it moves right
