At what point in its motion is the kinetic energy of the end of a pendulum greatest? at what point is its potential energy greatest when it's kinetic energy is half its greatest value how much potential energy did it gain

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?

If the textbook weighs 19.6 newtons on venus,what is the strength of gravity on venus?

Acar is traveling 35 mph on a smooth surface . if a balanced force is applied to the car what happens?
