Answer:

you'll momentarily accelerate from the wall at about 0.8 m/s²

Step-by-step explanation:

Given;

force exerted on the wall next to you, F = 50-N

your mass, m = 60 kg

According to Newton's third law of motion, action and reaction are equal and opposite, thus if you exert a force of 50-N on the wall, the wall will exert an equal force to you.

Force on the wall = force on you

From Newton's second law of motion;

F = ma

a = F/m

where;

a is your acceleration from the wall

m is your mass and

F is the force on the wall

a = 50 / 60

a = 0.83 m/s²

Thus, you'll momentarily accelerate from the wall at about 0.8 m/s²

Answer:

A. 0.8 m/s²

Step-by-step explanation:

Parameters given:

Force exerted on the wall, F = 50 N

Mass, m = 60kg

We know that force, F, is given as the product of mass and acceleration.

Mathematically, it is given as:

F = ma

Where a = acceleration

Therefore, acceleration will be:

a = F/m

a = 50/60

a = 0.833 m/s² (approximately 0.8 m/s²)

The acceleration of the skater is 0.8 m/s².
