Lesson Worksheet: Newton’s Second Law: Constant Mass Mathematics
In this worksheet, we will practice using Newton’s second law of motion with a particle with constant mass under the action of constant force.
A body of mass 37 kg was placed on a smooth horizontal surface where a force 72 N was acting on the body such that its line of action made an angle of downward from the vertical. Determine the acceleration of the body and the magnitude of the normal reaction . Round your answers to the nearest two decimal places.
A body of mass 41 kg was moving along a horizontal road at 14 m/s. A force started acting on the body opposing its motion. As a result, over the next 26 m, its speed decreased uniformly to 12 m/s. Find the magnitude of the force which caused this change in the body’s motion.
A tank of mass 41 metric tons started moving along a section of horizontal ground. The resistance to its motion was 9 newtons per metric ton of its mass, and the magnitude of the force generated by its engine was 1,450 N. Determine the tank’s speed 472 seconds after it started moving rounding the result to the nearest two decimal places.
