The rate at which the skiers accelerate is 2.7 m/s.
What is force?
A force applied to a body can change the magnitude of the momentum or its direction or both. Newton's second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and an (acceleration) are both vector quantities.
What is Ma in force?
Newton's second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of the object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object's acceleration.
