If a 5kg object experiences a 10 N force for a duration of 0.10 second then what is the momentum change of the object.
Well, well, well! We have an object here that's getting a little push. Let's calculate the momentum change, shall we?
Momentum (p) can be calculated using the formula:
p = m * v
But first, let's find the initial velocity (vi) of the object. If it experiences a force (F) for a certain duration of time (t), we can use Newton's second law (F = ma) to calculate the acceleration (a):
F = m * a
10 N = 5 kg * a
Now, we can find the acceleration:
a = 10 N / 5 kg = 2 m/s²
Since we have the initial velocity (vi = 0 m/s) and the acceleration (a = 2 m/s²), we can use the equation:
vf = vi + a * t
The final velocity (vf) is given by:
vf = 0 m/s + 2 m/s² * 0.10 s = 0.2 m/s
Finally, we can calculate the momentum change using the formula:
Δp = m * (vf - vi)
Δp = 5 kg * (0.2 m/s - 0 m/s)
Δp = 1 kg·m/s
So, my friend, the momentum change of the object is 1 kg·m/s.
To calculate the momentum change of an object, you can use the formula:
Momentum change (Δp) = Force (F) × time (Δt)
In this case:
Force (F) = 10 N
Time (Δt) = 0.10 second
Now, we can substitute the values into the formula to find the momentum change:
Δp = 10 N × 0.10 s
Δp = 1 N·s
Therefore, the momentum change of the object is 1 N·s.
To find the momentum change of an object, we can use the formula:
Momentum change = Force × Time
Given:
Force = 10 N
Time = 0.10 s
By substituting these values into the formula, we can calculate the momentum change:
Momentum change = 10 N × 0.10 s
To calculate this product, multiply the force (10 N) by the time (0.10 s):
Momentum change = 1 N·s
Therefore, the momentum change of the object is 1 N·s.
force = rate of change of momentum which is m a if the mass is constant
10 Newtons = change of momentum/0.10 second
so change of momentum = 1 kg m/s
by the way the change in speed would be 1/5 = .2 m/s
