My answer to the problem is as follows:
<span>1. Use the kinematic formula
Vf = Vi + a*t
for a, Vi = 3.0 m/s, a = 0.5 m/s/s, and t = 7.o s.
for b, Vf = 0, Vi = 3.0 m/s, and a = -0.60 m/s/s.
I hope my answer has come to your help. God bless and have a nice day ahead!

The result of a wave generator traveling faster than the speed of a wave is called as a boom. If the wave is a sound wave, it is called a sonic boom. However, if the wave is light, it is called as a luminal boom. Luminal bloom happens in some industries and is commonly called as the Cherenkov radiation.
1). Calculate how long it takes an object to fall 4,000 m after it's dropped. (Use D = (1/2) (g) (T²) . D is 4,000 m. g = 9.8 m/s². Find T .)
2). Calculate how far the object will move HORIZONTALLY in that length of time, if it's moving at 75 m/s. (Distance = (75 m/s) x (time) . )
