The image above shows two opposite forces acting on a rope. what can we say is true if the forces on each side of the rope is doubled to 150 newtons? a) it cannot be determined without knowing which man is stronger. b) the forces are not balanced, because one man is standing taller than the other. c) the forces are balanced. but, the forces acting on the rope have increased and the rope’s motion is affected. d) the forces are balanced. thus, there is no change in forces acting on the rope and the rope’s motion is not affected.

How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

The slope of a velocity time graph over any interval of time gives the during that interval
