Amy is in-line skating. Her mass is 50 kg. She is rolling forward (north) on a flat section of road at 10 m/s. The rolling frict
Licemer1 [7]

Answer:

The right solution is "0.50 m/s²". A further explanation is provided below.

Explanation:

The given values are:

Mass,

m = 50 kg

Speed,

v = 10 m/s

Rolling friction acting backward (south),

f = 10 N

Air resistance acting backward (south),

F_T = 15 N

The total force acting will be:

⇒  F = -f-F

On substituting the given values, we get

⇒      =-10-15

⇒      =-25 \ N

Now,

⇒  a = \frac{F}{m}

On substituting the given values, we get

⇒     =\frac{-25}{50}

⇒     =-0.50 \ m/s^2

The horizontal acceleration will be "0.50 m/s²" because the (-)ve sign indicates it in south direction.
