An object can be accelerating if it changes direction
Answer:
T=157.06 N
Explanation:
Given that
Mass of first block = 21.1 kg
Mass of second block = 12.9 kg
First mass is heavier than first that is why mass second first will go downward and mass second will go upward.
Given that pulley and string is mass less that is why both mass will have same acceleration.So lets take their acceleration is 'a'.
So now from force equation
21.1 x 9.81 - 12.9 x 9.81 =(21.1+12.9) a
Lets tension in string is T
T=21.1(9.81-2.36) N
T=157.06 N
Astrology is the belief the positions of the stars and movements of the planets of the Solar System, and also asteroids and other stars, but not as much, have an influence on the events, lives, and behavior of people.
It depends on what is the reference frame where the velocity of the leaf (6 m/s) is measured.
If it is measured with respect to the creek, then the answer is simply "6 m/s south".
If it is measured with respect to the observer moving toward the leaf, then the velocity of the leaf relative to the ground is actually the sum between the velocity of the leaf relative to the observer (6 m/s south, so 6 m/s) and the velocity of the observer relative to the ground (2 m/s north, so -2 m/s):
and the direction is south.
