a soccer ball kicked with a force of 14.1 N accelerates at 6.8 m/s^2 to the right. What is the mass of the ball?
in units of Kg.
Have you heard of the equation
F = m a ?
It is called Newton's second law.
It can be rewritten as
m = F/a
The direction of the kick (right or left) doesn't matter.
Solve for the mass. It will be in kg if F is in Newtons and a is in m/s^2.
