Answer 1

Answer #1

b)

h = ho + ut - 0.5gt^2

h = 285 + 12 * 4 - 0.5* 9.8* 4^2

h = 254.6 m

===========

c)

v = u - gt

v = 12 - 9.8* 4

v = - 27.2 m/s

==========

d)

total time of flight

0 = 285 + 12 t - 4.9 t^2

solving for t

t = 8.95 s

=======

Comment in case any doubt, will reply for sure.. Goodluck

(10 pts) A water balloon is dropped vertically from a height of 44 m above the sidewalk. It lands on the feet of a person who is walking along the sidewalk at a constant velocity When the balloon is released at t 0, the person is i2 m from the point of impact. Ignoring air resistance effects, determine the walking speed of the person. You should calculate that the time to impact is approx. 3 s.]
