A 900-kg machine base is rolled along a concrete floor using a series of steel pipes with outside diameters of 100 mm. Knowing that the coefficient of rolling resistance is 0.5 mm between the pipes and the base and 1.25 mm between the pipes and the concrete floor, determine the magnitude of the force P required to slowly move the base along the floor.
A 2.04-kg steel ball is dropped from a plane to an ocean. If the velocity of the ball just before reaching the water is 17 m/s and if the resistance in the water is 1.1v, what is the distance travelled by the object after 4.7 seconds? Answer in four decimal places.
1) Suppose that a body moves through a resisting medium with resistanceproportional to its velocity v, so that dv/dt=-kv. It is known that a body’s initial velocity of v0 is observed at location x0.a. Estimate the body’s velocity and the position at any time t>0 correctly.b. Conclude that the body travels only a finite distance and determine thatdistance correctly.

The standard specifies that footwear should be tested threetimes: with the person standing on only the left shoe; with theperson standing on only the right shoe; and with the personstanding on the pair. Do you expect the resistance of the personstanding on the left shoe alone to be larger than, smaller than,or the same as the resistance of the person standing on the pair,when measured under the test conditions?
