Mike is mowing his lawn. The force exerted on a lawn mower is 51 N. The mass of the mower is 24 kg. What is its acceleration?
Will my answer be a is a=F net/m I will then enter the known value given as a=51n / 24kg which will = to substituting the units of kilograms times the meters per square second for the newton yields such as a=51kgm/s2/24kg=2.1m/s2
F = m A
so
A = F/m = 51/24 = 2.1 m/s^2
so I agree
Yes, you are correct in using the equation a = F/net/m to find the acceleration. To clarify the calculation, the equation can be rearranged as a = F/m.
Given that the force exerted on the lawn mower is 51 N and the mass of the mower is 24 kg, you can substitute these values into the equation.
a = 51 N / 24 kg
Now, when you divide the units of Newton by the units of kilogram, you get meters per square second (m/s^2) since the Newton is equivalent to kg * m/s^2.
a = 51 kg * m/s^2 / 24 kg
Simplifying further, the kilograms cancel out, resulting in the equation:
a = 2.125 m/s^2
Therefore, the acceleration of the lawn mower is 2.125 m/s^2.
