A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. Match the answers with questions. (Hint: Clearly draw the force vector and displacement vector for all cases.) Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 5.0 m 15.0 v What is the angle between the weight force vector and the displacement vector? A. 15° v What is the angle between the normal force vector and the displacement vector? В. 90° v What is the angle between the friction force vector and the displacement vector?

Figure shows the velocity graph of a 65 kg student in an elevator. What is the student's apparent weight (magnitude only) at t = 7.0 s, in Newtons? Use g = 10.0 m/s². (Hint: What is the net force?) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Vy (m/s) 8- 4- (s) 10 4. 6. 8.

a = 5 m b = 3 m C = 1 m Mass of block = 120 kg Use g = 9.80665 m/s^2 2 m D 2.5 m B Find the Tension of Cord AC in N. If the calculated answer is not whole number, express it in 4 significant figures. If the value is negative, include a negative sign.

As shown in the figure, the mass of the block is 214 kg. If Fappi= 59.4 N and Fapp2=38.7 N, find the normal force. Fapp. Fopps FR
