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
There is no change. The bike is moving along a horizontal surface, and only a change in height can change the gravitational PE.
It is moving a figure horizontally and/or vertically but keeping it of the same size and orientation.
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.
In
15 meters north. the object is only moving away from the original starting place. its not like its moving away and then back again.
20 meters per second
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.
Moving directly straight either horizontally or vertically. As if walking on a straight line.

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.
The charge will be moving at a constant speed when it reaches an infinite distance from the two charges.
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
It is moving a figure horizontally and/or vertically but keeping it of the same size and orientation.
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.
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.
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.
Because the rain is moving vertically downward and the car is moving horizontally that's why the motion of the rain is slant.
