A sprinter with a mass of 70 kg accelerates at a rate of 5 m/s2. What force is the sprinter exerting?
To find the force exerted by the sprinter, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m * a).
Given:
mass (m) = 70 kg
acceleration (a) = 5 m/s²
Using the formula:
force (F) = mass (m) * acceleration (a)
Plugging in the values, we get:
F = 70 kg * 5 m/s²
F = 350 kg * m/s²
So, the force exerted by the sprinter is 350 kg * m/s².
