Newton’s second law states that force is the product of
mass and acceleration. This is expressed mathematically as:
F = m * a
Where F = force, m = mass, a = acceleration
Since in the given problem, the force is constant or same
force is acting upon two objects. Therefore we can simply equate the expression
m * a of the 2 objects.
m1 * a1 = m2 * a2
Where m1 = 2 kg, a1 = 38 m/s^2, m2 = 19 kg. Therefore
finding for a2:
2 kg * 38 m/s^2 = 19 kg * a2
<span>a2 = 4 m/s^2 (ANSWER)</span>
Since the question above is looking for the SPEEd of the WAVE, the formula that should be used is SPEED = DISTANCE / TIME. You just need to substitute the distance (36 meters) and the time (15 seconds) to the formula. You should be able to get SPEED = 2.4 m/s.
Answer:
Paint can which is placed higher than other can will have more potential energy. Because according to the definition of the potential energy an object placed at some higher place when released to the ground will have greater impact than the one placed at some lower place. Painter can give the other can more potential energy by placing it at some height greater than the other cans.
Explanation:
To understand this, we need to understand the concept of potential energy.
Let’s assume two objects A and B. If A is placed at 10 meters above the ground and if B is placed 20 meters above the ground then according to the definition of potential energy, object B will have greater potential energy.
Similarly, in our question, we have paint cans, one is carried at some higher place through a ladder by the painter will have greater potential energy as compared to the one which is placed at ground.
Paint can which is placed higher than other can will have more potential energy. Because according to the definition of the potential energy an object placed at some higher place when released to the ground will have greater impact than the one placed at some lower place. Painter can give the other can more potential energy by placing it at some height greater than the other cans.
