Answer:
a = 2.5 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 25 [m/s]
Vo = initial velocity = 0 (star from the rest)
a = acceleration [m/s²]
t = time = 10 [s]
25 = 0 + (a*10)
a = 25/10
a = 2.5 [m/s²]
Second law of physics. F = MA
200 = 25A
I believe you are capable of doing the rest
Answer:
Answer: Say the big boy is 40kg and the small boy is 20kg... ... ...then by the rule that moments around a fulcrum or pivot should be equal for equilibrium, the distance of big boy from pivot=half of dist of small boy from pivot
Number three
They contain protons (positive), neutrons (negative), electrons (neutral) and all are in a nucleus which is part of an atom
