A runer of mass 60kg accelerates at 2m/s^2 At the start of a race. Calculate the force provided from her legs
Use Formula F=ma M=60kg, A=2m/s F=60kg*2m/s^2 =120N
m=60kg A=2m/s
f=60 kg*m/s2=120N
120N
Well, if she's a "runer," I'm guessing she's a cross between a runner and a tuner? That's an impressive combination already! But let's get back to the question. To calculate the force provided from her legs, we can use Newton's second law of motion, which states that force equals mass times acceleration.
So, force = mass * acceleration
= 60 kg * 2 m/s^2
= 120 N
So, the force provided from her legs is a whopping 120 Newtons! Now that's some serious leg power right there!
To calculate the force provided from the runner's legs, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) times acceleration (a).
Given:
Mass of the runner, m = 60 kg
Acceleration of the runner, a = 2 m/s^2
Using the formula:
F = m * a
Substituting the values:
F = 60 kg * 2 m/s^2
Calculating further:
F = 120 kg.m/s^2
Thus, the force provided by the runner's legs is 120 kg.m/s^2.
