A flat cushion of mass m is released from rest at the corner of the roof...

A flat cushion of mass m is released from rest at the corner of the roof of a building, at height h. A wind blowing along the side of the building exerts a constant horizontal force of magnitude F on the cushion as it drops as shown in the figure below. The air exerts no vertical force.

(A) Show that the path of the cushion is a straight line. (Submit a file with a maximum size of 1 MB.)

(B) Does the cushion fall with constant velocity?

(c) If m = 1.19 kg, h = 8.20 m, and F = 2.12 N, how far from the building (in m) will the cushion hit the level ground?

(D) If the cushion is thrown downward with a nonzero speed at the top of the building, what will be the shape of its trajectory?

A block of mass M = 4.0kg is released from rest at point A as shown. Part AB of the track is frictionless and is one quarter of a circle of radius R=1.25m. The horizontal part of the track BC is rough with co-efficient of kinetic friction . The block comes to rest at C after moving a distance L = 6.25m. The block can be treated as a point particle. [a] What is the speed (in m/s) of M...

1.) In the figure, a block of mass m = 13 kg is released from rest on a frictionless incline of angle θ = 30°. Below the block is a spring that can be compressed 3.7 cm by a force of 210 N. The block momentarily stops when it compresses the spring by 6.0 cm. (a) How far does the block move down the incline from its rest position to this stopping point? (b) What is the speed of the...

A box with mass m = 2.2kg on an inclined frictionless surface is released from rest from a height h = 2.35 m . After reaching the bottom of the incline the box slides with friction (coefficient of kinetic friction = 1.2) along a horizontal surface until coming to a rest after a distance d. 1. Draw a free body diagram for the box while it is on the incline. Clearly label all forces with standard names. 2. Draw a...

An object of mass 2 kg is released from rest from a platform 30 m above the water and allowed to fall under the influence of gravity. After the object strikes the water, it begins to sink with gravity pulling down and a buoyancy force pushing up. Assume that the force due to gravity (g = 9.81 m/s2) is constant, no change in momentum occurs on impact with the water, the buoyancy force is 1/2 the weight (weight=mg), and the...

A playground is on the flat roof of a city school, 4.9 m above the street below (see figure). The vertical wall of the building is h = 6.40 m high, to form a 1.5-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of θ = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The...
