Using the initial momentum vector as a basis, the change in momentum vector Δp for the cart is drawn as shown in the attachment.
<h3>Further explanation</h3>
Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

F = Force ( Newton )
m = Object's Mass ( kg )
a = Acceleration ( m )
Let us now tackle the problem !

<u>Given:</u>
Initial speed of cart = v_i = v
Final speed of cart = v_f = v
<u>Unknown:</u>
The change in momentum of cart = I = ?
<u>Solution:</u>









<em>From the results above, we can conclude that the change in momentum vector Δp is twice the initial momentum vector p_i but in opposite direction.</em>
The vector <em>Δp could be drawn as shown </em><em>in the attachment.</em>

Answer:
A = 10 m amplitude
m = 3 kg mass of object
Vm = 5 m/s
w A = Vm where w = omega
w = 2 * pi * f
2 * pi * f 10 = 5
f = 5 / (20 * pi) = .0796 / sec
Average speed of the runner is the rate at which the runner covers the total distance. Average speed of the runner in the race is given by,
Average speed = 
Where
Total distance = Distance covered by the runner from initial to final position
Total time = time taken by the runner to cover entire distance
Instantaneous speed is the speed of the runner at the particular moment in the given time. Instantaneous speed is given by,
Instantaneous speed = 
x = position of the runner at time t
t = time taken to cover distance x
Hence, Average speed and instantaneous speed are different for a runner running in the race.
Multiply (Saturn radii) by (60,268) to get the distance in kilometers.
(This is the radius of the planet, not it's orbit.)
Answer:
4 m/s
Explanation:
Momentum is conserved.
m₁ v₁ + m₂ v₂ = (m₁ + m₂) v
(50)(5) + (20)(1.5) = (50 + 20) v
v = 4
The final velocity is 4 m/s.
