Use Newton's second law to determine the acceleration being applied to the sled. There are three forces at work on the sled (its weight, the force normal to the ground, and friction) but two of them cancel, leaving friction as the only effective force. This vector is pointed in the opposite direction of the sled's movement, so if we take the direction of its movement to be the positive axis, we would find the acceleration due to the friction to be

Now we use the formula

to find the distance it travels. The sled comes to a rest, so
, and let's take the starting position
to be the origin. Then the distance traveled
is

Electrostatics is described as the study of electric charges that can be collected and held in place.
The above given statement is a true st
Answer:

Explanation:
Given that,
Force force acting on the Skater's rocket is 220 N
Resistive force acting on it, F' = 30 N
Mass of Shelby, m = 60 kg
We need to find the acceleration of Shelby. Net force acting on Shelby is given by :
Net force = 220-30
= 190 N
The formula of net force is :
F = ma
a is acceleration of Shelby

So, the acceleration of Shelby is 
Yeah science is hard. Hopefully you do good in it :)
