A truck runs into a pile of sand, moving 1.6 m as it slows to a stop. The magnitude of the work that the sand does on the truck is 6.0×105J.
Determine the magnitude of the average force that the sand exerts on the truck. Did the sand do positive or negative work? How does the magnitude of the average force change if the stopping distance is doubled? Assume that the work that the sand does on the truck remains unchanged.
Homework Answers
Work = force * perpendicular distance
W = F*d
6*10^5 = F*1.6
F = 3.75*10^5 N
if the stopping distance is doubled , The force will be halved

Chapter 5 Q:6
A car that weighs 1.2 x 104 N is initially moving at a speed of 37 km/h when the brakes are applied and the car is brought to a stop in 20 m. Assuming that the force that stops the car is constant, find (a) the magnitude of that force and (b) the time required for the change in speed. If the initial speed is doubled, and the car experiences the same force during the braking, by...

A car with mass MC = 1.44 x 103 kg runs into the back of a truck with mass MT = 3.19 x 103 kg that is initially at rest. Immediately after the collision, the car is moving with a speed of 1.04 m/s and the truck is moving with a speed of 2.53 m/s, both in the direction the car was initially traveling. What is the total kinetic energy lost in the collision? (Of course, the change in energy...

A 10 kg penguin with an initial velocity of 6.0 m/s toward the
east runs onto a large area of level, frictionless ice. As the
penguin slides across the ice, it is pushed by the wind with a
force that is constant in magnitude and direction. The figure shows
the position of the penguin, at 1.0 s intervals, as it slides on
the ice; the positive direction of the x axis is toward
the east. The penguin first makes contact...

Most of us know intuitively that in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Why is this? Many people imagine that the collision force exerted on the car is much greater than that experienced by the truck. To substantiate this view, they point out that the car is crushed, whereas the truck in only dented. This idea of unequal forces, of course, is...
