In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free-fall acceleration to be 9.80 m/s2 . Ignore air resistance.

A flea jumps straight up to a maximum height of 0.450 m . What is its initial velocity v0 as it leaves the ground?

How long is the flea in the air from the time it jumps to the time it hits the ground?

Solutions

Expert Solution

Maximum height reached by the flea is

Initial velocity of flea

Final velocity of flea at the maximum height is

Acceleration of the flea is

Using kinematic equation,

Initial velocity of flea is

---------------------

Using kinematic equation

As you know, the motion of an object is described by the kinematic equations that you learned in your first semester of introductory physics. For two dimensional projectile motion, where the trajectory of an object is described by an upside down parabola, with constant acceleration ~a = ~g, these equations are: x = x0 + vx0t vx = vx0 y = y0 + vy0t − 1 2 gt2 vy = vy0 − gt v 2 y = v 2 y0...

When studying the motion of an object, we can analyze it using kinematic equations or energy equations. Both types of equations give information about position and velocity. Kinematic equations give information about the motion of an object from moment to moment, while energy equations typically detail the initial and final points of the motion. Consider a car traveling at 6 m/s. When the driver breaks the car travels 18 meters before coming to a stop. (This is one question, just...

In the figure, we must apply a force of magnitude 82.0 N to hold the block stationary at x = -2.00 cm. From that position, we then slowly move the block so that our force does +7.00 J of work on the spring–block system; the block is then again stationary. What are the block's positions?

In this problem you will apply the utility maximization framework to try to understand some of the effects of the current banking crisis on consumers wellbeing. Take a two period model in which consumers utility function is U(C1,C2)=C1C2 where C1 is consumption in period 1 and C2 consumption in period 2, both retrieved in cash. The consumer is free to borrow or save in period one as the interest rate r, through the banking system. a) Write the consumer's inter-temporal...
