A block of ice with mass 4.00 kg is initially at rest on a frictionless, horizontal surface.
Question:
A block of ice with mass 4.00 kg is initially at rest on a frictionless, horizontal surface. A worker then applies a horizontal force F to it. As a result, the block moves along the x-axis such that its position as a function of time is given by x(t) = αt2 + βt2, where α = 0.200 m/s2 and β = 0.0200 m/s3.
(a) Calculate the velocity of the object when t = 4.00 s.
(b) Calculate the magnitude of F when t = 4.00 s.
(c) Calculate the work done by the force F during the first 4.00 s of the motion.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
