Three monkeys a, b, and c weighing 20, 26, and 25 lb, respectively, are climbing up and down the rope suspended from d. at the instant represented, a is descending the rope with an acceleration of 4.2 ft/sec2, and c is pulling himself up with an acceleration of 5.4 ft/sec2. monkey b is climbing up with a constant speed of 4.0 ft/sec. treat the rope and monkeys as a complete system and calculate the tension t in the rope at d.

Explanation:

Given

Mass of monkey A=20lb

Mass of monkey B=26lb

Mass of monkey C=25lb

acceleration of monkey A=

acceleration of monkey B=0

acceleration of monkey C=

Force Due to monkey A

Force Due to monkey A

Force Due to monkey A

In addition to it  Weights of monkeys will be acting downwards therefore net Downwards force is balanced by tension

T=

answer: option c.

explanation:

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.
