Answer:
a. 10.0 J
Explanation:
Given parameters:
Weight of bowling ball = 10N
Height of building = 5m
Distance of fall = 1m
Unknown:
Kinetic energy of the ball = ?
Solution:
Kinetic energy is the energy due to the motion of a body.
Mathematically;
K.E = mv²
Since this body is falling under gravity;
K.E = mgh
mg = weight of the ball
h is the height
Insert the parameters and solve;
K.E = 10 x 1
K.E = 10J
<span>We know that the momentum keeps constant in a inelastic collisions, so the product of mass and speed do not change:
m1 * v1 + m2 * v2 = m * v
1 * 1 + 5 * 0 = (1 + 5) * v
1 = 6 * v
v = 1/6 m/s
So the final speed of the 6 kg chunk will travel at 0.167 m/s</span>
When an object vibrates in simple harmonic motion in the vertical direction, its minimum speed occurs when it is at <em>either endpoint</em> ... either the highest point or the lowest point.
At those points, it reverses its direction, so its speed is zero for an instant.
Both Distance and displacement deals the distance of the object but they differ distinct is scalr quantity and displacement is vector quantity or have Direction
The first and third, because it only produces odd partials.
