Question

Hong the x-axis h article's maxim True or False: 9 must be negative. Why or why not? Des this partic C. A 3.5-kg object is dropped from an 80-story building. The object falls y meters in t seconds. Assuming the object is in free fall, how far does the object fall in 2t seconds? Show your work/reasoning a. y b. 2y c. y/2 d. 3y e. y/3 Page 4 of 9 cle's maxim

Answer 1

c. mass of the object (m) = 3.5 kg displacement (s)- y metries time a t seconds. Let acceleration = am/2 By using equation of motion se ut t hat? > y = oxt that? => az ay t2 How s time is at seconds utt at? = oxat + 1 x 24 x (26) 2 t2 = uy Đ ans.
