Iwo bodies are end of attached to passed sking which Pulley, so that they hang vertically. If mass of the body B is 4 kg; find a mass 0.05 m 식 up with of the body a which acceleration Take ake g=10ms )
acceleration = (change in speed) / (time for the change)
change in speed = (20-120)= -100 m/s.
1.5 min = 90 sec
acceleration = -100/90 = -1.11 m/s^2.
we don't care about the 150kg or the 2,500 meters. they don't make any difference.

Answer from: Quest
the simple machine has three main features. they are:
loadfulcrumeffort
fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.
the keisha 's machine labels are
x : load
y: fulcrum
z: lever

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.
hope this ! : )

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
