A 6.15 kg block is pulled by a rope up a ramp with an incline of 25 degrees from the horizontal. The acceleration of the block is 2.45 m/s^2. The coefficient of friction between the block and the ramp is 0.266. What is the tension in the rope?
Homework Answers
Fnet = FT - m*g*sin(25) - μ*k*m*g*cos(25)
m*a = FT - m*g*sin(25) - μ*k*m*g*cos(25)
FT = m*(a + g*sin(25) + μ*k*g*cos(25))
= 6.15*(2.45 + 9.81*sin(25) + 0.266*9.81*cos(25))
= 55.11 N

Block 1 (20 kg) is pulled by a rope from left to right up a ramp which is inclined 45 degrees from the horizontal. The rope pulls on block 1 with a force of 360 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.2. Assume that the x-axis is parallel to the incline and positive in the direction up the incline. What is the magnitude of the...

A block (m1 = 3.7 kg) is being pulled up a ramp (at an angle = 36.4 degrees from the horizontal) with a cable that is parallel to the ramp's surface. The cable runs over a pulley that is at the top of the ramp and then is attached to a hanging block (m2 = 17 kg). What is the tension in the cable? Assume that the coefficient of kinetic friction for the block on the ramp is 0.2.

A 7.55-kg box is pulled up a ramp that is inclined at an angle of 39.0° with respect to the horizontal, as shown below. The coefficient of kinetic friction between the box and the ramp is 0.145, and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of 3.09 m/s2, what must the tension Fr in the rope be? Use g 9.81 m/s2 for the acceleration due to gravity....
