v2 = u2 + 2as where v = current velocity, u = initial velocity, a = acceleration, and s = displacement. Taking a = - 9.8 ms-2 v2 = 182 - (9.8 x 11 x 2) = 108.4 v = 10.4 ms-1

As the speed of a bicycle moving along a horizontal surface increases from 2 meters per second to 4 meters per second the bicycle's gravitational potential energy?
There is no change. The bike is moving along a horizontal surface, and only a change in height can change the gravitational PE.
It takes the person 5 seconds to move 10 meters What is the power output?
The person's speed is 2 meters per second. The power required for him to accomplish that depends on his weight, on his efficiency of movement, on whether he's moving horizontally or vertically, etc., all of which the question neglects to specify.
What is a displacement in math?
It is moving a figure horizontally and/or vertically but keeping it of the same size and orientation.
What are two advantages of moving an object up a ramp instead of lifting it vertically?
Expending or using less energy to overcome gravity's pull to move the object,2) better leverage in moving it to a greater height and distance. But first you have to overcome friction using rollers,rope and pulleys...once it starts to move keep going.
What would be the displacement of an object going 5 meters north and then another 10 meters north?
15 meters north. the object is only moving away from the original starting place. its not like its moving away and then back again.
You drop a 5 kilo ball from rest from a height of 20 meters how fast is it moving when it strikes the ground?
20 meters per second
At the end of a game a player on the winning team throws the ball straight up as high as he can throw it at the top of its path the basketballs velocity is what?
At the very top of the ball's path, its velocity is momentarily zero. This is because as the ball reaches its maximum height, it stops moving vertically before falling back down due to gravity.
What is moving?
Moving directly straight either horizontally or vertically. As if walking on a straight line.

When Rae dropped a bowling ball from a height of 8 meters At which distance above the ground was the ball most likely moving at the greatest speed?
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.

What veritables determine how fast an object will be moving when it reaches terminal velocity?
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
What is a displacement in math?
It is moving a figure horizontally and/or vertically but keeping it of the same size and orientation.
Can a body have accelaration with zero velociety?
Yes, but only for an instant. Throw a rock or a baseball straight up. After a while, it reaches its maximum height, stops moving up, and starts moving down. From the time it leaves your hand, its acceleration is constant. But at the very top of the arc, where it's changing from moving up to moving down, at that instant, it has zero velocity.
What is the boy throw a stone vertically upward with an initial velocity of 6.0 ms?
The boy throws a stone vertically upward with an initial velocity of 6.0 m/s, meaning the stone is moving against gravity. It will reach a maximum height and then fall back down due to gravity. The stone will eventually return to the ground after reaching its highest point.
What are the ways in which heat is transfeered vertically?
Heat can be transferred vertically through conduction when heat moves through a material, convection when heat is carried by a fluid moving vertically, and radiation when heat is emitted in the form of electromagnetic waves. Each mechanism plays a role in transferring heat vertically in different contexts.
Why does rain slant on cars when the car is in motion?
Because the rain is moving vertically downward and the car is moving horizontally that's why the motion of the rain is slant.
