Answer:
A. 0.8 m/s²
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.
Answer:
you'll momentarily accelerate from the wall at about 0.8 m/s²
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
