<h2>
Speed with which it return to its initial level is 100 m/s</h2>
Explanation:
We have equation of motion v² = u² + 2as
Initial velocity, u = 100 m/s
Acceleration, a = -9.81 m/s²
Final velocity, v = ?
Displacement, s = 0 m
Substituting
v² = u² + 2as
v² = 100² + 2 x -9.81 x 0
v² = 100²
v = ±100 m/s
+100 m/s is initial velocity and -100 m/s is final velocity.
Speed with which it return to its initial level is 100 m/s
Answer: Yes the further the sun is away the longer the shadow is. At noon,the shadow is the shortest because its straight up above you. If this helps pls mark brainliest!
Vf =Vi + at
Vi =Vf - at
= 34 - 15•13
= - 161 m/s :/
the independent variables are the different
laudry detergent
the dependent variable is color of the cloth
after washing
the control variables are the amount of water
added and by washing one cloth b just water
<span>hypothesis: the cloth washed with laundry
detergent is cleaner than the cloth that is just washed by water. </span>
6^2 + 8^2 = 36 + 64 = 100
sqrt(100) = 10 m/s northwest
