A mass of .1539 kg. moves down a 5 meter ramp in 2 seconds. What is the velocity and the KE developed by the moving mass?
V = 5m/2s = 2.5 m/s.
KE = M*V^2/2 = 1539*2.5^2/2 = 4809 J.
To determine the velocity of the moving mass, we can use the formula:
velocity = distance / time
Given that the distance is 5 meters and the time is 2 seconds, we can substitute these values into the formula:
velocity = 5 meters / 2 seconds
velocity = 2.5 meters/second
Therefore, the velocity of the moving mass is 2.5 meters/second.
To calculate the kinetic energy (KE) developed by the moving mass, we can use the formula:
kinetic energy = 0.5 * mass * velocity^2
Substituting the given mass of 0.1539 kg and the calculated velocity of 2.5 m/s, we can calculate the KE:
kinetic energy = 0.5 * 0.1539 kg * (2.5 m/s)^2
kinetic energy = 0.5 * 0.1539 kg * 6.25 m^2/s^2
kinetic energy = 0.4809375 Joules
Therefore, the kinetic energy developed by the moving mass is approximately 0.481 Joules.
To find the velocity and kinetic energy (KE) of the moving mass, we need to use some equations.
First, let's calculate the velocity. We can use the equation:
velocity (v) = displacement (d) / time (t)
Given that the displacement is 5 meters and the time is 2 seconds, we can plug in these values:
v = 5 m / 2 s
v = 2.5 m/s
Therefore, the velocity of the mass is 2.5 m/s.
Now, let's calculate the kinetic energy. The formula for kinetic energy is:
KE = 0.5 * mass * velocity^2
Given that the mass is 0.1539 kg and the velocity is 2.5 m/s, we can substitute these values:
KE = 0.5 * 0.1539 kg * (2.5 m/s)^2
Calculating the square of velocity:
KE = 0.5 * 0.1539 kg * 6.25 m^2/s^2
Finally, calculating the kinetic energy:
KE = 0.4809375 Joules
Therefore, the kinetic energy developed by the moving mass is approximately 0.4809375 Joules.
