<span>Kinetic
energy is the energy that is possessed by an object that is moving. It is
calculated by one-half the product of the mass and the square of the velocity
of the object. We need to determine the velocity of the cart that is moving.

First, we use Newton's Second Law of motion;
<span>Force = ma
200 = 55a
a = 3.64 m/s^2
Then, from the kinematic equation we calculate the velocity;
v^2 = v0^2 + 2ax
where v is the final velocity, v0 is the initial veocity (zero since it initially start at zero), a is the acceleration ( 3.64 m/s^2) and x is the distance traveled.
v^2 = 0^2 + 2 (3.64) (10)
v^2 = 72.73 m^2 / s^2
v = 8.53 m / s
KE = mv^2 / 2
KE = 1/2 (55) (8.53^2)
KE= 2000 J</span>
Answer:
Is this your ans of this question
Answer:
a powerplay for the other team, and a penalty kill for the team with the player in the box
Explanation:
B. Kilopascals.
A kilopascal equals to 1,000 pascals; and a pascal is equal to a force of 1 newton per square meter.
Meanwhile,
- a gram and a kilogram are both units of measurement for mass, and
- a newton is a unit of measurement for force.
