A 40 kg monkey climbs a rope with an upward acceleration of 2 m/s² (g = 10 m/s²). The tension in the rope is:

Answer: 480 N.

A 320 N
B 400 N
C 480 N
D 800 N

Correct answer: C. 480 N

Explanation: T = m(g + a) = 40(10 + 2) = 480 N.

Free-body diagram of a block on an incline: weight (mg) resolves into mg sinθ along the slope and mg cosθ into the slope, balanced by the normal force N and friction f.

Concept context

Newton's three laws, friction, circular motion, and free body diagrams.
