Question
In the figure below, the net external force on the 30-kg mower is stated to be 60 N. Please, note that
Fnet is the vector sum of force of the person and force of friction on the mover.
Fret
a. If the force of friction opposing the motion is 10 N, what is the magnitude of the force F exerted by
the person on the mower in Newtons?
Hint
The magnitude of force F exerted by the person on the mower is equal to
N.
Enter an integer or decimal number [more..]
b. Suppose the mower is moving at 1.5 m/s when the force F is removed. How far in meters will the
mower go before stopping?
Hint
Once the force F is removed, the mower will go 1.125
stopping.
x m before
