Froghoppers may be the insect jumping champs. These 6-mm-long bugs can spring 70 cm into the air, about the same distance as the flea. But the froghopper is 60 times more massive than a 12-mg flea. The froghopper pushes off for about 4 mm. Determine the average force that the froghopper exerts on the surface.

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)?...

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)?...

A short wire of length 62.3 cm is repelled by a long straight wire that carries a current of 1.6 A and runs parallel to it. A spring of stiffness 2.34 kg/s2 presses the short wire to the long one. When a current is passed through the short wire, it pushes away from the long one until it reaches a distance 1.88 mm from it. (a) What is the field coming off of the wire? μT (b) What is the...

2.) A 15 cm long tendon was found to stretch 3.7 mm by a force of 13.4 N. The tendon was approximately cylindrical, with an average diameter of 8.5 mm. (a) Calculate Young's modulus of this tendon. (b) If we wanted to model this tendon as a spring, what would we use for the spring constant k? Hint: Try writing the force in the form |F distance stretched] and then compare with Hooke's Law |F= kAx. stuff] x
