if the F,net is unkown the m in kg is 4.5 and 1.2 m/s2 so what is the f net
To calculate the net force, you can use the formula:
F_net = m*a
Where:
F_net = net force (in Newtons)
m = mass (in kg) = 4.5 kg
a = acceleration (in m/s^2) = 1.2 m/s^2
Substitute the given values into the formula:
F_net = 4.5 kg * 1.2 m/s^2
F_net = 5.4 N
Therefore, the net force is 5.4 Newtons.
