if a person is pushing a cart with a force of 40 Newtons and it accelerates at 0.5 m/s2 , what is the mass of the cart ?
F = m A
40 = m * 0.5
m = 40 * 2 kilograms
To find the mass of the cart, we can use Newton's second law of motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration.
The formula for Newton's second law is:
F = m * a
Where:
F = force applied to the object (40 Newtons)
m = mass of the cart (unknown)
a = acceleration of the cart (0.5 m/s^2)
We can rearrange the formula to solve for the mass:
m = F / a
Plugging in the values:
m = 40 Newtons / 0.5 m/s^2
m = 80 kilograms
So, the mass of the cart is 80 kilograms.
