A 12.0 kg box is pulled along a horizontal surface by a force Fp at a 30° angle above the horizontal. The coefficient of static friction is ?s = 0.4 and the coefficient of kinetic friction is ?k = 0.3.
a) Show that a minimum of 44 N force must be applied at the given 30° angle to get the box moving.
b) Calculate the acceleration of the box assuming a force of magnitude 45 N is applied at the 30° angle.
A jogger travels a route that has two parts. The first is a displacement of 2.70 km due south, and the second involves a displacement that points due east.
In a period of 1.0 s, 5.0 x10^23 nitrogen molecules strike a wall of area 7.80 cm2. If the molecules move at 270 m/s and strike wall head on in a perfectly elastic collision, find the pressure exerted on the wall. (The mass of one N2 molecule is 4..
Two masses traveling at the same speed v0 collide head on. Nothing is known about collision other than that it is not completely inelastic.
Explain the sign of the acceleration and describe in words how the thread changes the velocity of the spider. would also like to know how to get to the answer can any one explain this to me in english?
