The driver of a 1,200kg car travelling with a velocity of 27.0m/s slams on his brakes when he realizes traffic ahead of him has come to a stop. If a force of kinetic friction of -7,500N acts on the car and he applies the brakes 45.0m from the car in front of him, with what velocity will he strike the vehicle?
After given a push, a 1.0-kg box slides down a slope that is inclined by 30◦ relative to the horizontal. There isa spring with a spring constant of 1000 N/m attached to the bottom of the slope, as shown. The surface ofthe slope is rough and has a coefficient of kinetic friction of 0.15. After being pushed, the box has an initialvelocity v0, and it then slides 1.2 m down the slope before hitting the spring, where it compresses the springby 25 cm. Find the work done on the box by gravity, friction, and the spring. Also, find the initial speed ofthe box.
Listen> Read the scenario. A cyclist is riding his bike at a constant speed of 5 m/s, and experiences a frictional force between the bike and sidewalk of 100 N. The cyclist then changes his speed to 10 m/s. What effect does this increase in speed have on the frictional force between the bike and sidewalk? The frictional force doubles because when speed increases frictional force also increases. The frictional force between the bike and sidewalk stays the same because speed does not affect frictional force. The frictional force becomes half of what it was because when speed increases, frictional force decreases. The frictional force increases, but does not double because although friction increases with increasing speed, it does not increase as fast. Next >

In February 1955, a paratrooper fell 360 m from an airplane without being able to open his chute but happened to land in snow, suffering only minor injuries. Assume that his speed at impact was 52 m/s (terminal speed), that his mass (including gear) was 80 kg, and that the force on him from the snow was at the survivable limit of 1.2 x 105 N. (a) What is the minimum depth of snow that would have stopped him safely? m (b) What is the magnitude of the impulse on him from the snow? kg-m/s
