question : net force of 225 N accelerates a bike and rider at 2.65m/s^2. What is the mass of the bike and rider together ?
m =F/a =225/2.65 = 84.9 kg
Read somthing about the Second Law!
To find the mass of the bike and rider together, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration.
Given:
Net force (F) = 225 N
Acceleration (a) = 2.65 m/s^2
Using the formula F = ma and rearranging it to solve for mass (m), we get:
m = F/a
Substituting the given values into the formula, we have:
m = 225 N / 2.65 m/s^2
m ≈ 84.91 kg
Therefore, the mass of the bike and rider together is approximately 84.91 kg.
To find the mass of the bike and rider together, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
The formula is:
Net Force (F) = Mass (m) x Acceleration (a)
Rearranging the formula, we can solve for the mass (m):
Mass (m) = Net Force (F) / Acceleration (a)
Given:
Net Force (F) = 225 N
Acceleration (a) = 2.65 m/s^2
Now, substitute these values into the formula and calculate:
Mass (m) = 225 N / 2.65 m/s^2
Mass (m) = 85.15 kg
Therefore, the mass of the bike and rider together is approximately 85.15 kg.
F=ma
solve for mass.
