Impulse is the change of momentum before and after the collision:
I = mv₁ - mv₂ = m (v₁-v₂)
m mass
v velocity
Impuls also is defined as the average force during a short period of time:
I = F * t = m * a * t
F average force
t time difference
m mass
a average acceleration
Combined:
m(v₁- v₂) = m * a * t
a = (v₁- v₂) / t
= (4m/s - (-3m/s)) / 6s - 5s
= 7m/s / 1s
= 7 m/s²
Answer:
Explanation:
<u><em>Newton's Third Law of Motion States that:</em></u>
"For every action, there is a reaction which is equal in magnitude but opposite in direction."
Newton's third law is also called "Law of Interaction".

Answer:
Explanation:
The change in momentum of the ball is equal to the impulse exerted on it, therefore:
where
is the change in momentum
F is the average force exerted on the ball
is the time during which the force is applied
In this problem,
F = 156 N
So, the change in momentum of the ball is
Answer: 588.9 m/s
Explanation:
Given that :
θ = 30°
Height, h = 3400m
Time, t = 10 seconds
From trigonometry ;
Tanθ = opposite / hypotenus
Tan 30 = 3400 / x
x tan 30 = 3400
0.5773502x = 3400
x = 3400 / 0.5773502
x = 5888.9727
Recall ;
Speed = Distance / time
Speed = 5888.9727 / 10
Speed = 588.897 m/s
Speed = 588.9 m/s
A. Relativity
B. Thermodynamics
C. Electromagnetism
