Answer:
31.2m/s
Explanation:
final velocity = initial velocity + acceleration • time
final velocity = 0 m/s + 6.58m/s/s • 4.74 s
final velocity = 31.2 m/s
Answer: A-they change the direction of the forces
Explanation:
Any device which makes our work simpler is known as a machine. A machine may increase the amount of output force which is determined by its mechanical advantage or a machine changes the direction of the force.
In the given situation the input force acts in the downward direction to pull the rope. The output force acts on the flag being pulled upwards at the other end. Thus, the direction of the forces varies. Correct option is A.
Answer:
Virtually all the mass of an atom resides in its nucleus, according to Chemistry
Explanation:
Answer:
735N
Explanation:
Weight is a measurement of force.
F = Force
m = mass
a = acceleration
F = m*a
F = 75kg*9.8m/s²
F = 735N
