An object of mass 20 kg is released from rest and allowed to fall under the influence of gravity. Assume that the force in Newtons due to air resistance is -28v where v is the velocity of the object in m/s. If it is initially dropped from a height of 800 meters, approximately how long will it take to reach the ground? Use x (t) as the distance below the point from where it was dropped.

A boxer's fist and glove have a mass of m = 1.04 kg. The boxer's fist can obtain a speed of v = 9.25 m/s in a time of t = 0.21 s. Write a symbolic expression for the magnitude of the average acceleration, aave, of the boxer's fist, in terms of the variables provided. Find the magnitude of the average acceleration, aave, in meters per square second. Write an expression for the magnitude of the average net force, Fb, that the boxer must apply to his fist to achieve the given velocity. (Write the expression in terms of m, v and t.) What is the numerical value of Fb, in newtons?

Problem 3: An object is thrown off the top of a building with velocity 32 m/s at an angle of 17° with respect to the horizontal.

An airplane needs to drop a package of supplies to a team in a remote location (landing is not possible). The plane is flying 112.8 m above the ground at a speed of 196.8 m/s. We know that the plane should NOT drop the package when it is passing directly over the location. Instead, the plane needs to drop the supplies BEFORE it reaches the location. How far out (in meters) should the supplies be dropped? (in other words, how far horiszontally will the package go as it falls?) Ignore air resistance.
A ball of mass 500g and diameter 30 cm is thrown upward with an initial speed of 15.1m/s. If we include the effects of air resistance, what is the velocity of the ball after it has traveled three quarters the time it takes to reach its highest point?
You are an engineer in charge of designing a new generation of elevators for a prospective upgrade to the Empire State Building. Before the state legislature votes on funding for the project, they would like you to prepare a report on the benefits of upgrading the elevators. One of the numbers that they have requested is the time it will take the elevator to go from the ground floor to the 102nd floor observatory. They are unlikely to approve the project unless the new elevators make the trip much faster than the old elevators. If state law mandates that elevators cannot accelerate more than 1.80 m/s2 or travel faster than 14.8 m/s, what is the minimum time in which an elevator can travel the 373 m from the ground floor to the observatory floor? minimum travel time:
A ball is thrown horizontally from 43 a meter high cliff and lands on the ground 70.6 m from the base of the cliff. What was the ball's initial velocity in m/s?
