A flea jumps by exerting a force of 1.32 × 10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 1.20 x 10-6 N on the flea. Find the direction and magnitude (in m/s2) of the acceleration of the flea if its mass is 6.0 x 10-7 kg. (Let us assume that F points to the right. We will consider this to be the +x direction and vertical to be the ty direction.) magnitude direction wind m/s² ° (measured clockwise from the vertical)

In the figure below, a box of Cheerios (mass mc = 1.5 kg) and a box of Wheaties (mass mw = 2.7 kg) are accelerated across a horizontal surface by a horizontal force F applied to the Cheerios box. The magnitude of the frictional force on the Cheerios box is 2.0 N, and the magnitude of the frictional force on the Wheaties box is 4.1 N. If the magnitude of F is 12 N, what is the magnitude of the force on the Wheaties box from the Cheerios box? |---Select--- mc Mw

Three polarizing sheets are stacked. The first and third are crossed; the one between has its polarizing direction at 45.0° to the polarizing directions of the other two.What fraction of the intensity of an originally unpolarized beam is transmitted by the stack?

An 8.6 kg body undergoes an acceleration of 2.7 m/s2. What is the magnitude of the resultant force acting on it (in N)? If this same force is applied to a 5.2 kg body, what is the magnitude of the acceleration (in m/s2)?

You are trying to escape a hoard of zombies and must make an elevator to get down a cliff as fast as possible.  As you cannot hit the ground faster than 10m/s and the cliff is 25m deep, this limits your acceleration to 2 m/s2 (you will want to accelerate at this rate to get down the cliff as fast as you can).  Assuming your and the bucket’s mass together is 100kg (m2) , what is the minimum mass (m1) that the sled must be to prevent your death (assume the ground is frictionless).

A skydiver weighing 178 lbf (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 17s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is 0.76 |v| when the parachute is closed and 12 |v| when the parachute is open, where the velocity v is measured in ft/s. Use g = 32 ft/s². Round your answers to two decimal places. (a) Find the speed of the skydiver when the parachute opens. v(17) = i ft/s (b) Find the distance fallen before the parachute opens. x(17) = i ft (c) What is the limiting velocity v after the parachute opens? VL = i ft/s

A hockey puck slides with an initial speed of 56.7 m/s on a large frozen lake. The coefficient of kinetic friction between the puck and the ice is 0.05. What is the acceleration on the hockey puck caused by friction? Assume the puck's velocity is in the positive-x direction. And what is the speed of the puck after 6 s?

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

Superman is applying a 17,000 N horizontal force to try and stop a speeding locomotive.  This train has a mass of {9004} kg, it is on level, horizontal track, and gravity in Metropolis is 10 N/kg.  The train is originally travelling at 25 m/s, and the brakes have failed. (Friction force is zero).   Draw a Force Body Diagram of the train, labelling and calculating all forces. What is the acceleration of the train? How many seconds does it take for Superman to stop the train? How far does the train travel in that time?
