Resultant force= (2*6^2)^(1/2)
=8.5m/s
answer is B.
Answer:
the formula of mechanical advantage is
MA = load / effort
VR = effort distance / load distance

Answer:
Explanation:
For spring

where n is frequency of oscillation and k is force constant and m is mass
Putting the values

k = .4032 N/m
F= k x
where F is force , k is force constant and x is extension
Putting the given values
1 = .4032 x
x = 2.48 m
Answer:Newton's 2nd law
Explanation:Newton's 2nd law also states that the rate at which an object changes speed is proportional to the force that is exerted. Engines provide thrust and accelerate a plane forward along the runway. If the engines supply a small force, only a small acceleration will result.
