Square root of (4^2 + 4^2) = 4*squareRoot(2)
To attain equilibrium there should be net force on the body, so that the object will not be in motion. so for a body of wb, any weight will do as long as there is no external force that is applied to it. the only force that is acting on it is the weight which is going down, and the normal force which is going up, to counter act the weight. and the net force is zero.
The answer you are looking for is 22 mph.
Solution:
s=speed
d=distance
t=time
Setting up the formula for the speed of an object with distance and time:
s=d/t
Substituting the given values,
s=88 miles/4 hours
So, therefore, the final answer is 22 mph.
I hope this helped answer your question for you. Good day to you.
The correct answer to the question is : C)The problem is asking to solve for work; W = F × d
EXPLANATION:
As per the question, the distance covered by the object d = 29 m.
The force that acts on the object is F = 289 N.
We are asked to choose the correct equation for work done.
Work is said to be done on a body or by a body if the applied force has a component along the direction of displacement.
Mathematically work done W = force × displacement
= F × d
As per the question, we are given distance covered and applied force.
Hence, the correct equation for calculating work done by the object is equation C.
