Calculate the time needed for a net force of 5N to change the velocity of a 10kg mass by 2m
F = M*a. 5 = 10*a, a = 0.5 m/s^2.
a = (V-Vo)/t.
0.5 = 2/t, t = 4 s.
To calculate the time needed for a net force to change the velocity of a mass, we can use Newton's second law:
F = ma
where F is the net force, m is the mass, and a is the acceleration.
In this case, the net force is 5N and the mass is 10kg. We need to find the acceleration first in order to calculate the time.
Since we know the net force, we can rearrange the formula to find the acceleration:
a = F/m
a = 5N / 10kg
a = 0.5 m/s^2
Now, to find the time needed to change the velocity by 2m, we can use the following equation:
v = at
where v is the change in velocity and t is the time. Rearranging the formula to solve for time, we have:
t = v/a
t = 2m / 0.5 m/s^2
t = 4 seconds
Therefore, it would take 4 seconds for a net force of 5N to change the velocity of a 10kg mass by 2m.
To calculate the time needed for a net force to change the velocity of an object, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied and inversely proportional to the mass of the object. The formula for this is:
F = m * a
Rearranging the formula, we can solve for acceleration:
a = F / m
Given that the force (F) is 5N and the mass (m) is 10kg, we can substitute these values into the formula to find the acceleration:
a = 5N / 10kg = 0.5 m/s^2
Next, we can use the kinematic equation to find the time (t) needed to change the velocity (Δv) of the object. The formula for this is:
Δv = a * t
We know that the change in velocity (Δv) is 2m, and the acceleration (a) is 0.5 m/s^2. Substituting these values into the formula, we can solve for time:
2m = 0.5 m/s^2 * t
Simplifying the equation:
t = 2m / (0.5 m/s^2)
t = 4s
Therefore, it would take 4 seconds for a net force of 5N to change the velocity of a 10kg mass by 2m.
