Final answer:
To find the acceleration of an 80 kg person pushed with a force of 240 N, we use Newton's second law (F = m x a). After rearranging the formula to solve for acceleration (a = F/m), the person's acceleration is found to be 3 m/s².
Step-by-step explanation:
To calculate the acceleration of an 80 kg person on a sled who is pushed with a force of 240 N, we would use Newton's second law of motion. This law states that the acceleration (a) of an object is directly proportional to the net force (F) acting upon it and inversely proportional to its total mass (m).
The formula derived from Newton's second law is:
F = m × a,
where F is the force applied, m is the total mass, and a is the acceleration. To find the acceleration, we rearrange theformula to solve for a:
a = F/m
Plugging in the given values:
a = 240 N / 80 kg
a = 3 m/s²
Thus, the person's acceleration is 3 meters per second squared.
