Danielle is applying 25.2 N to the right on her sled. The sled has a mass of 15.7 kg, and
1 answer:
The applied force is parallel to the ground, so the net vertical force on the sled is 0. By Newton's second law, this means the normal force and weight of the sled cancel out:
<em>n</em> - <em>w</em> = 0
<em>n</em> = <em>w</em>
<em>n</em> = <em>m g</em>
<em>n</em> = (15.7 kg) (9.80 m/s²)
<em>n</em> = 153.86 N
