An electron is accelerated by a uniform electric field (1000 V/m) pointing vertically upward. 1) Use Newton’s laws to determine the electron’s velocity after it moves 0.10 cm from rest. 2) Find the speed using the energy method. That is, consider the electric potential energy change and conversion to kinetic

Asmall 21 kilogram canoe is floating downriver at a speed of 1 m/s. what is the canoe's kinetic energy?

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

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?
