On average, froghopper insects have a mass of 11.3 mg and jump to a height of 423 mm. The takeoff velocity is achieved as the little critter extends its legs over a distance of approximately 2.00 mm. Assume that the +y-direction is upward, and assume a vertical jump with constant acceleration. What is the froghopper's acceleration ajump during the jump (the jump itself, not the time in the air)? Ajump = m/s? During the jump itself, how much time t are the froghopper's feet in contact with the ground? t = S What force n does the ground exert on the froghopper during the jump itself? Express your answer in millinewtons.

A:

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.
