Question:
A 7.7-N force pulls horizontally on a 1.6-kg block that slides on a smooth horizontal surface. This block is connected by a horizontal string to a second block of mass m2 = 0.83 kg on the same surface.
(a) What is the acceleration of the blocks?
(b) What is the tension in the string?
(c) If the mass of block 1 is increased, does the tension in the string increase, decrease, or stay the same?
Step by Step Answer:
Write Newtons second law for each block and add the equations to elimin...View the full answer

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.
