A block of weight w = 30.0N sits on a frictionless inclined plane, which makes an angle θ = 24.0 degree with respect to the horizontal. A force of magnitude F = 12.2N , applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. The block moves up an incline with constant speed. Required:
What is the total work Wtotal done on the block by all forces as the block moves a distance L = 4.10m up the incline?

Write a question about how changing temperature affects the gas inside the sports ball

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?
