Suppose the block has a mass of 1.4 kg and an initial speed of 0.62 m/s. (a)
Question:
Suppose the block has a mass of 1.4 kg and an initial speed of 0.62 m/s.
(a) What force constant must the spring have if the maximum compression is to be 2.4 cm?
(b) If the spring has the force constant found in part (a), find the maximum compression if the mass of the block is doubled and its initial speed is halved.

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.
