Question 1) A flea jumps by exerting a force of 1.22 10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 1.12 10-6 N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.0 10-7 kg. (Let us assume that Fwind points to the right. We will consider this to be the +x direction and vertical to be the +y...

Suppose you exert a force of 190 N tangential to the outer edge
of a 1.585-m radius 75.5-kg grindstone (which is a solid disk).
a. What is the torque τ, in newton meters, you are
exerting on the grindstone, relative to the center of mass of the
grindstone? (I believe the answer is
301.15)
b. What is the angular acceleration of the grindstone
α0, in radians per square second, assuming
negligible friction?
c. What is the angular acceleration of the...

An airplane has a mass of 29,500 kg and takes off under the influence of a constant net force of 42,000 N. What is the net force that acts on the plane's 77 kg pilot?
Suppose you are a space traveler, and you land on the surface of a strange new planet
Suppose you are a space traveler, and you land on the surface of a strange new planet. As stated in your Starfleet Manual, your first job is to measure the acceleration due to gravity, g, on this planet. You construct an "Atwood machine", which consists of two masses connected to a pulley by a string of negligible mass, as shown in the figure. One of the masses is m1 = 50.0 kg and the other is m2 = 39.0 kg....

Use the worked example above to help you solve this problem. An
airplane has wings, each with area 4.05 m2, designed so
that air flows over the top of the wing at 249 m/s and underneath
the wing at 226 m/s. Find the mass of the airplane such that the
lift on the plane will support its weight, assuming the force from
the pressure difference across the wings is directed straight
upwards.
Your response differs from the correct...

One end of a spring with a force constant of k 10.0 N/m is attached to the end of a long horizontal frictionless track and the other end is attached to a mass m = 2.20 kg which glides along the track. After you establish the equilibrium position of the mass-spring system, you move the mass in the negative direction (to the left), compressing the spring 1.73 m. You then release the mass from rest and start your stopwatch, that...
