While rollerblading through your neighborhood, you suddenly lose control and begin coasting down a hill, unable to stop. Fortunately, you see a neighbor moving a mattress into their house and decide that colliding with the mattress would be far less painful than the alternatives. Your plan works to perfection and you are slowed gently over the course of 1.4 seconds. Assuming your mass is 80 kg and your initial velocity was 10 m/s, find the average force applied on your body by the mattress (in N).

Let us make the (unrealistic) assumption that a boat of mass m gliding with initial velocity v0 in water is slowed by a viscous retarding force of magnitude bv2, where b is a constant, (a) Find and sketch v(t). How long does it take the boat to reach a speed of v0/l000? (b) Find x(t). How far does the boat travel in this time? Let m = 200 kg, v0 = 2 m/s, and b = 0.2 Nm-2s2.
You push an object, initially at rest, across a frictionless floor with a constant force for a time interval t, resulting in a final speed of v for the object. You then repeat the experiment, but with a force that is twice as large. What time interval is now required to reach the same final speed v? (a) 4 t (b) 2 t (c) t (d) t/2 (e) t/4

A person with a black belt in karate has a fist that has a mass of 0.70 kg. Starting from rest, this fist attains a velocity of 6.3 m/s in 0.15 s. What is the magnitude of the average net force applied to the fist to achieve this level of performance?
A barefoot field-goal kicker imparts a speedof 44 m/s to a football initially at rest.If the football has a mass of 0.41 kg and thetime of contact with the ball is 0.033 s, whatis the magnitude of the force exerted by theball on the kicker’s foot?Answer in units of N.
A 70 kg bicyclist is riding her 15 kg bicycle downhill on a road with a slope of 80without pedaling or braking. The bicyclist has a frontal area of 0.45 m2and a dragcoefficient of 1.1 in the upright position, and a frontal area of 0.4 m2and a dragcoefficient of 0.9 in a racing position. If the downhill speed of the bicyclist(terminal velocity) can be determined when the total force acting on the “body” inthe direction of movement is equal to zero, determine the percentage of downspeed that she can be increased when she is in a racing position. Air temperatureis 150C and disregarding the rolling resistance and friction at the bearing.

In the very Dutch sport of Fierljeppen, athletes run up to a long pole and then use it to vault across a canal. At the very top of his arc, a 55 kg vaulter is moving at 2.5 m/s and is 5.1 m from the bottom end of the pole. What vertical force does the pole exert on the vaulter?

Two penguins, Wheezy and Mumble, are racing down an icy slope into the water below. Wheezy has a mass of 22 kg. Mumble has a mass of 25 kg. The slope is angled at eight degrees to the horizontal. They both start from the same position at the same time, and slide down the icy slope entirely due to gravity alone. There is a coefficient of kinetic friction of 0.12 between the penguins and the ice. Who wins the race and what is the winner's acceleration when they reach the finish line (ie the water)?
Imagine 4 objects made of the same material but with different masses. All systems have the same coefficient of static friction μs. Rank in order from smallest to largest: the minimum applied force required to make the objects move if their masses are: Object 1 = m/2 Object 2 = m Object 3 = 2m Object 4 = 4m imagine three objects with the same coefficient of kinetic friction but each having a different mass. We’re going to push each object with a known force F. Rank the velocity of the objects, from smallest to greatest, after we apply the force F for 4 seconds Now think about a robot pushing an object across a horizontal surface without friction and draw graphs for Force, acceleration, velocity, and position all vs. time for both situations.
