Two friends are pushing a stalled,
1610 kg car. the first pushes with
a 107 n forward force. the car
accelerates at 0.123 m/s . how much
force does the second person exert?
(unit = n)

91.03 N

Explanation:

consider the way the forces are acting on the car , in the graph

assume the car is accelerating to the right

we can apply Newton's second law of motion (F = ma )

→ F = ma

Fpush + 107 = 1610 * 0.123

Fpush = 91.03 N

second guy is applying 91.03 N force on the car

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.
