M1 has a mass of 5.790 kg. It is on a horizontal surface, connected by a massless string to a hook where mass M2 can be increased smoothly. The pulley has a negligible mass and no friction. When M2 = 3.092 kg it begins to accelerate downwards at a rate of 2.328 m/s2. Calculate ms-mk between M1...
A pendulum has a length L = 1.14 m. It hangs straight down in a jet plane about to take off as shown by the dotted line in the figure. The jet accelerates uniformly, and during that time, the pendulum oscillates about the equilibrium position shown by the solid line, with D = 0.42 m. What is the...
Two forces F1 and F2 are acting on a mass M=6.0 kg. The force F1 = 7.0i + 5.0j + 6.0k, in N. The acceleration of the mass is given by a = 1.0i + 3.0j + 3.0k, in m/s2. Calculate the magnitude of F2.
I understand that when adding these forces you just add like terms, the i's j's and k's...
Five vectors are listed below. Select them in order of increasing magnitudes, from shortest to longest. If B is smallest, then A, C, D, and finally E is the largest, enter BACDE (Note: If of equal length, then enter in the order listed.)
A) 17i-23j-23k
B) 22i+30j
C) 18i-28j-26k
D) 37k...
Block on frictionless floor!
A 3.70 kg block located on a horizontal frictionless floor is pulled by a cord that exerts a force F=13.0 N at an angle q= 25.0° above the horizontal, as shown.
What is the speed of the block 3.70 seconds after it starts moving?
I have drawn a picture...
