In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction
V = at + V0
where v0 is the initial speed, a is the acceleration and t is the time.
So:
v = 5m/s^2*5s + 25m/s = 50 m/s
Answer:
A) Inertia
Explanation:
Inertia is why objects tend to resist changes in their motion. Like a rolling ball will keep rolling unless we try to add friction to it, which then would stop the ball.
Answer:
6 V
Explanation:
In a circuit, the relationship between voltage, current and resistance is given by Ohm's law:
where
V is the voltage
R is the resistance
I is the current
In this circuit, we have
is the resistance
I = 0.500 A
so we can find the voltage of the battery by using Ohm's law:
