You are pushing a friend on a sled. You push with a force of 20N. Your friend and the sled together have a mass of 60kg. Ignoring friction, what is the acceleration of your friend on the sled?
F = M*a. = 20.
a = 20/M = 20/60 = 0.333 m/s^2.
To find the acceleration of your friend on the sled, you can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).
In this case, the force you are applying is 20N, and the combined mass of your friend and the sled is 60kg. Therefore, the equation becomes:
20N = 60kg * a
To find the acceleration (a), you need to rearrange the equation:
a = 20N / 60kg
a = 1/3 m/s²
So the acceleration of your friend on the sled is 1/3 m/s².
To find the acceleration of your friend on the sled, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
The formula for Newton's second law is:
F = m * a
Where:
F = Net force applied (in newtons, N)
m = Mass of the object (in kilograms, kg)
a = Acceleration of the object (in meters per second squared, m/s^2)
In this case, the net force applied is the force you exert on the sled, which is 20N. The mass of your friend and the sled combined is 60kg.
Plugging these values into the formula, we get:
20N = 60kg * a
To find the value of the acceleration (a), we rearrange the equation:
a = 20N / 60kg
a ≈ 0.33 m/s^2
Therefore, the acceleration of your friend on the sled, ignoring friction, is approximately 0.33 m/s^2.
