When a large truck is turning right or left you should?

Watch the right and left turns because the truck will often swing wide to make and complete any turn. Maintain a distance where you can see the truck’s side view mirrors while traveling behind the truck.

When traveling behind a motorcycle you should?

Generally, it’s best to give a three or four second following distance when travelling behind a motorcyclist. It is also important that drivers be especially careful when near a motorcyclist and approaching an intersection.

When you are behind a motorcycle you should be ready to use your horn drive more slowly allow a larger following distance?

Allow a larger following distance. When following a motorcyclist, allow for at least a three- to four-second following distance. Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist.

What is a safe following distance for a motorcycle?

a 4 second

When passing large semi trucks you should not hang out in the area referred to as what?

A truck’s blind spots are called No Zones. A No Zone is the area around the trucks where your car is no longer visible or you are so close that the truck can’t stop or maneuver safely.

How do you calculate the force of impact?

F = m * v² / (2 * d) ,

  1. F is the average impact force,
  2. m is the mass of an object,
  3. v is the initial speed of an object,
  4. d is the distance traveled during collision.

How do you calculate the impact force of a hammer?

When there is a dent, we can estimate the time by dividing the depth of the dent by the initial speed of the hammer. A typical dent is on the order of a millimeter, and a typical hammer speed at impact is probably ~ 10 meters/sec. The duration of the impact would be approximately equal to 1/10,000 sec.

How do you find the force of something hitting the ground?

You should know force= mass x acceleration, and acceleration is the rate of change of velocity over time. So what you need to know is how quickly it stops when it hits the ground.

How do you calculate the impulse needed to stop an object?

The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.

How do you calculate the work required to stop an object?

To stop the object the work required to be done is 2 kJ W =-2000 J = – 2 kJ. Thus, to stop the object the work required to be done is 2 kJ.

What is the work done on an object if its initial and final kinetic energies are the same?

Equations. The net work on an object is equal to the object’s final kinetic energy minus the initial kinetic energy.
