Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

1) A small steel block and a magnet rest on a horizontal frictionless table. The steel block weighs 0.07N and the magnet is fixed to the table. The force acting on the steel block by the magnet is inversely proportional to the square of the distance between the steel block and the magnet. When the block is 26cm away from the magnet, the force becomes 0.145N. If the block starts its motion from rest at this position, what is the magnitude of the velocity of the block when it is 9.5cm away from the magnet?

This question is similar to the question above but read and calculate carefully. The situation has changed and the numbers have changed. Bonita Cart Bonita is again pulling a cart to the right. The cart used to be tied to a wall but now the rope has broken so the cart rolls over the horizontal floor without friction. Assume that the only forces on the cart are tension forces (including the force from Bonita), normal forces, and gravity with g = 9.81 m/s?. Bonita's shoes do not slide over the floor. Bonita has a mass of 52 kg. The cart has a mass of 45 kg. The mass of the rope is small enough to be ignored. Bonita is pulling the cart with a constant force of 283 newtons. Calculate the magnitude of the force that the cart exerts on Bonita. Note that the magnitude of a force is a positive quantity.

In a rope-climbing competition, all of the lifting is done by the arms; legs can only dangle. Imagine 220-lb Garvin Smith in training, hanging stationary from the rope, his legs off the floor. When prompted by his coach, he rapidly lifts his center of mass by 4 ft. in 0.65 s. Calculate Garvin Smith's acceleration. Round the final answer to one decimal place. Determine the net force (“force imbalance”) producing the acceleration. Round the final answer to one decimal place. Which forces are acting on Smith? (Note that his arms are part of himself, so they cannot exert a force on Smith.) With what magnitude force is Smith pulling down on the rope? Round the final answer to one decimal place.
