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.
Velocity is the speed of an object in a given direction. It is typically measured in meters/second.

The final speed of an object in free fall is known as terminal velocity. Terminal velocity on Earth can range from 54 meters per second (in SI units) to 90 meters per second based on aerodynamics.
The same speed: the image will always appear to be at a point exactly behind the mirror as the object is in front.
In circular motion an object accelerates towards the radius of the circle but its velocity is unchanged
20 meters per second
When a net force acts on that object, there is a change in velocity, and thus acceleration.
the answer to this question can be found using the following simple equation:Vf = 9.8t + ViVf = Velocity Final (m/s)Vi = Velocity Initial (m/s)t = Time (s)For your specific problem, providing the object wasn't moving at the start of the 4 second period, the answer is 39.2 meters per second.
Use the formula for centripetal acceleration: velocity squared / radius.

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.
Its kinetic energy (in joules) will be (31) times (its velocity in meters per second)2 .
