you push a friend on a sled your friend and the sled together have a mass of 70 kg if the net force is 33N what is the seld's acceleration?
F = ma
33 = 70a
a = 33/70
To find the sled's acceleration, we'll use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The equation can be stated as:
F_net = m * a
Where:
F_net is the net force acting on the sled,
m is the mass of the sled, and
a is the acceleration of the sled.
In this case, the net force acting on the sled is 33 N and the mass of the sled is 70 kg. So, we can rearrange the equation to solve for the acceleration:
a = F_net / m
Substituting the given values, we have:
a = 33 N / 70 kg
Calculating this, we get:
a ≈ 0.47 m/s²
Therefore, the sled's acceleration is approximately 0.47 m/s².
To determine the sled's acceleration, you can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The equation that represents this relationship is:
F = ma
Where:
F = Net force applied (in Newtons)
m = Mass of the object (in kilograms)
a = Acceleration of the object (in meters per second squared)
Given:
Net force (F) = 33 N
Mass of sled and friend (m) = 70 kg
To find the sled's acceleration (a), rearrange the formula as follows:
a = F / m
Substitute the given values into the equation:
a = 33 N / 70 kg
a ≈ 0.47 m/s²
Therefore, the sled's acceleration is approximately 0.47 meters per second squared.
using formula: f=ma or a=f/m
a=33/70
therefore: a=0.47m/s^2
