Force = rate of change of momentum = 0.16(38 + 44)/0.002 = 6560 N
Answer:
third
Explanation:
for every action there is an equal and opposite reaction
example
bouncing ball
ball receives a force from the ground due to collision
that same force causes the ball to bounce off the ground
first law:
inertia
example
stuff in space doesn't move unless its pushed
then it keeps going unless something stops it
second law
force = mass times acceleration
example
harder you push a cart the faster it goes
the less a cart weighs the faster a cart goes

Beats only occur when the frequency of two objects is interfere with one another and when those objects are made to identical amplitudes together.
(a) The time the baseball spends in the air is 0.92 s.
(b) The horizontal distance from the roof edge to the point where the baseball lands on the ground is 3.1 m.
<h3>
Time spent in air by the baseball</h3>
h = vt - ¹/₂gt²
-2.1 = (4.05 x sin 34)t - ¹/₂(9.8)(t²)
-2.1 = 2.26t - 4.9t²
4.9t² - 2.26t - 2.1 = 0
t = 0.92 s
<h3>Horizontal distance traveled by the baseball</h3>
R = Vx(t)
R = (4.05 x cos 34)(0.92)
R = 3.1 m
Thus, the time the baseball spends in the air is 0.92 s.
The horizontal distance from the roof edge to the point where the baseball lands on the ground is 3.1 m.
