Use the formula for centripetal acceleration: velocity squared / radius.
Momentum = (mass ) x (velocity) = (5) x (4) = 20 kg-meters/sec in the direction of the velocity.
Use the formula a = v2 / r, with v = velocity (speed, actually) in meters/second, r = radius in meters. The answer will be in meters per square second.
The speed of the the object is 20/5 = 4 metres per second.In order to answer the question in terms of velocity, it is necessary to know the direction of motion because velocity is a vector.
anything shot up with that initial velocity. There isn't anything in specific.
Gravity affects velocity by accelerating objects towards the Earth's surface, increasing their speed. As an object falls towards the ground, its velocity will increase due to the force of gravity acting upon it. Conversely, when an object is launched upwards, gravity will eventually cause it to slow down and fall back towards the ground.
Downward velocity refers to the speed at which an object is falling towards the ground or moving in a downward direction. It is commonly measured in units such as meters per second or feet per second. A positive downward velocity indicates the object is accelerating downward, while a negative velocity means the object is moving upward.
The product of mass in kilograms and velocity in meters per second is the momentum of the object, measured in kilogram-meters per second (kg*m/s).
One common example is when an object falls freely due to gravity. As the object accelerates towards the Earth, its velocity changes because gravity is constantly acting on it. The object's velocity increases as it falls towards the ground.
The decrease in magnitude velocity refers to the reduction in the speed of an object or particle. It indicates the change in the object's velocity moving towards a slower speed.
When an object is dropped from a height, gravity causes it to accelerate towards the ground. This acceleration leads to a change in velocity as the object's speed increases. The change in velocity occurs because gravity exerts a force on the object, pulling it towards the Earth.
The change in velocity of a falling object is due to gravity, causing it to accelerate continuously towards the ground. As the object falls, its velocity increases at a constant rate of approximately 9.8 m/s^2 (on Earth) until it reaches terminal velocity or impacts the ground.

Velocity is a vector quantity that describes the rate of change of an object's position with respect to time. It includes both the speed (magnitude of velocity) and the direction of motion. The SI unit for velocity is meters per second (m/s).
The same speed: the image will always appear to be at a point exactly behind the mirror as the object is in front.
The velocity of an object will increase as it falls towards the ground due to the acceleration of gravity. However, once it reaches terminal velocity, its velocity will remain constant.
The velocity of an object falling towards the surface of the Earth will increase approximately by 9.8 m/s every second due to gravity, assuming air resistance is negligible. This velocity will continue to increase until the object reaches its terminal velocity or collides with the Earth.
