Agrasshopper can jump a maximum horizontal distance of 40cm. if it spends negligible time on the ground then in this case its speed along horizontal road will be

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

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?

What is a good example of instantaneous speed
