what change in velocity would be produced by an unbalanced force of 2.0 x 10^4N acting for 6.0s on a 2000 kg dragster
F = ma
v = at
so,
∆v = 2.0*10^4/2000 * 6.0 = _____ m/s
what the answer
To calculate the change in velocity produced by an unbalanced force, we can use Newton's second law of motion. The formula is:
Force = mass x acceleration
Rearranging the formula, we get:
Acceleration = Force / mass
Given that the force is 2.0 x 10^4 N and the mass is 2000 kg, we can substitute these values into the equation:
Acceleration = (2.0 x 10^4 N) / (2000 kg)
Acceleration = 10 m/s²
Next, we can calculate the change in velocity using the formula:
Change in velocity = acceleration x time
Since the acceleration is 10 m/s² and the time is 6.0 seconds, we can substitute these values into the equation:
Change in velocity = (10 m/s²) x (6.0 s)
Change in velocity = 60 m/s
Therefore, the change in velocity produced by the unbalanced force of 2.0 x 10^4 N acting for 6.0 s on a 2000 kg dragster is 60 m/s.
To calculate the change in velocity produced by an unbalanced force, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a), or F = m * a.
In this case, we are given the force (F) as 2.0 x 10^4 N and the mass (m) as 2000 kg. We need to find the acceleration (a) first.
Using the formula F = m * a, we rearrange the equation to solve for acceleration:
a = F / m
a = (2.0 x 10^4 N) / (2000 kg)
a = 10 m/s^2
Now that we have the acceleration, we can calculate the change in velocity (Δv) using the equation of motion:
Δv = a * t
where t is the time for which the force is applied. Here, the time is given as 6.0 s.
Δv = (10 m/s^2) * (6.0 s)
Δv = 60 m/s
Therefore, the change in velocity produced by the unbalanced force of 2.0 x 10^4 N acting for 6.0 s on a 2000 kg dragster is 60 m/s.
