Newton’s second law of motion can also be described as _____.
anzhelika [568]

Answer:

F=ma

Explanation:

The Newton's laws of motion tries to explain the how bodies behave and the energy changes when theys are in motion. For the 3 of them to hold, the bodies must be moving in a straight line and with constant velocity.

The second one states that, "the change of momentum of a moving body is directly proportional to the force producing it and it takes place to the direction of force."

From the choices given, the appropriate answer is F=ma

Looking at the position of the house and the tree, if the man ran starting from the house going
Aleks04 [339]

Average velocity of man is 2 m/s

<u>Given that;</u>

Distance between tree and house = 16 m

Time taken = 8 seconds

<u>Find:</u>

Average<em> velocity</em>

<u>Computation:</u>

Average velocity = Total distance cover / Time taken

Average velocity = Distance between tree and house / Time taken

Average velocity = 16 / 8

Average velocity = 2 m/s

F a forklift raises a 76-kg load a distance of 2.5 m, about how much work has it done?
sleet_krkn [62]

W= FxD. Since the weight is not put into force you’re going to convert it by multiplying it by 9.8 (gravity). 76kg x 9.8 = 7448. Then multiply that by the distance (2.5). Your answer is 1862.
