anything shot up with that initial velocity. There isn't anything in specific.
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
If the initial velocity is 50 meters per second and the launch angle is 15 degrees what is the maximum height? Explain.
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.
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.
It means that the object's speed is always 5 meters per second faster than it was one second earlier.

Velocity is the speed of an object in a given direction. It is typically measured in meters/second.
AccelerationStep 1 Find the acceleration of the object, the time the object is being accelerated and the initial velocity. These values are usually given to you in the problem. If the force is given, find the acceleration by dividing the force on the object by its mass.Step 2 Convert all units to standard units. Acceleration should be in meters per second squared. Velocity should be in meters per second, and time should be in seconds.Step 3 Multiply the acceleration by the time the object is being accelerated. For example, if an object falls for 3 seconds, multiply 3 by 9.8 meters per second squared, which is the acceleration from gravity. The resultant velocity in this case is 29.4 meters per second.Step 4 Add this velocity to the initial velocity. In the example above, if the object had an initial velocity of 5 meters per second, the resultant velocity would be 34.4 meters per second. The overall formula here is v (final) - at + v (initial) where "v" is velocity, "a" is acceleration and "t" is time. In this example the equation would look like this: v (final) = 9.8 x 3 + 5, giving us a result of 34.4.After ImpactStep 1 Identify the initial velocity of the two objects, the mass of both objects and the final speed of either object if it is given. These values are usually given in the problem.Step 2 Convert all velocities to meters per second and all masses to kilograms.Step 3 Multiply the initial velocity of each object by its mass. Add these two products together to get the total momentum. For example, if both objects have a mass of 5 kilograms, one is at rest and the other is moving at 10 meters per second. The calculation would look like this: 5 x 10 + 5 x 0. This would give us a result of 50 kilogram-meters per second.Step 4 Divide the total momentum by the sum of the masses if the two objects stick together after impact. This will give you the resultant velocity of the two objects. In the example above, we would take 50 and divide by the sum of the masses, which is 10, getting a result of 5 meters per second.If the objects do not stick together, subtract the product of the mass and the final velocity of one object from the total initial momentum. Then, divide the difference by the mass of the other object. This will give you the resultant velocity of the other object. In the example from the previous step, if the final velocity of the object originally moving at 10 meters per second was 2 meters per second, our calculation would look like this: (50 - 10) / 5, which gives us a result of 8 meters per second.
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.
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.
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.
It means that the object's speed is always 5 meters per second faster than it was one second earlier.
When a net force acts on that object, there is a change in velocity, and thus acceleration.
The object will be moving at 14.7 meters per second. 1.5 seconds X 9.8 meters per second squared(the gravitational constant). This assumes that the object's original velocity is zero.

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.
