Froghopper insects have a typical mass of around 13.1 mg and can jump to a height of 45.8 cm. The takeoff velocity is achieved as the insect flexes its legs over a distance of approximately 2.00 mm. Assume that the jump is vertical and that the froghopper undergoes constant acceleration while its feet are in contact with the ground. Ignore air resistance. What is the acceleration of the insect during the time of the jump (before it leaves the ground)?...

Froghopper insects have a typical mass of around 11.5 mg and can jump to a height of 50.8 cm. The takeoff velocity is achieved as the insect flexes its legs over a distance of approximately 2.00 mm. Assume that the jump is vertical and that the froghopper undergoes constant acceleration while its feet are in contact with the ground. Ignore air resistance. What is the acceleration of the insect during the time of the jump (before it leaves the ground)?...

Susan performs a high jump where she has an initial vertical velocity of 4.04 m/s. If her center of gravity is 1.04 meters above the ground at takeoff, what is the maximum height she will be able to clear in meters (m) if her center of gravity needs to just clear the bar for the jump to be successful?

A 75-kg volleyball player performs a maximum-effort vertical jump with an initial velocity of 3 m/s. The player leaves the ground with an upright body position and also touches down with the same body position. Answer the following: ua A. How much will the player's center of mass (COM) travel in the air along the vertical direction during the ascending phase of the jump? Compute the maximum kinetic energy of the player during the jump. C. Compute the maximum potential...
