First you have to resolve all forces into vertical and horizontal. If it on a slope take the reaction force as vertical and the slope as horizontal. Then equate the opposite forces, for example the friction and the driving force, and use maths to figure out the resultant.
by using trig. So draw a triangle out with the given information. for example 1 line is 12m/s, another line is Um/s (u for unknown) and one line is resultant velocity. add your angle in and use trig to work out what you want.
An easy way to visual this is by drawing a triangle with the vectors. Obviously one vector will be the vertical and another will be perpendicular to that, the horizontal. These two vectors will connect at the ends. Then you connect the other two ends with another vector and that is the resultant. Vector sum, or the square root of the sum of the squares; you use the pythagorem theorem to find the resultant, also the hypotenuse. r2= v12 + v22. The vertical vector squared plus the horizontal squared, you take the root of the sum of the squared vectors and that gives the resultant vector. If the horizontal or vertical vector is negative, then the resultant vector will be negative as well. This is used for any units including velocity, distance, and acceleration.
This problem can be solved using the pythagorean theoremA2 + B2 = C2A = 90 km/hB = 50 km/h 902 + 502 = 10,600√10,600 = 103.0C = 103 km/h
Hammer piston velocity is: Velocity of an pneumatic cylinder can be calculated as s = 28.8 q / A (1) where s = velocity (inches/sec) q = volume flow (cubic feet/min)A = piston area (square inches) Do you know how to calculate the impact PSI? - This is where I get lost.
To find the acceleration of an object moving in a straight line, you must calculate the change in velocity during a unit of time. Acceleration is the rate of change of velocity over time, not distance. It is given by the formula acceleration = (final velocity - initial velocity) / time.
To calculate the resultant velocity of two velocities in the same direction, simply add the two velocities together. The resultant velocity will be the sum of the individual velocities.
When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.

To calculate the resultant velocity of two velocities in the same direction, simply add the magnitudes of the two velocities together. The direction of the resultant velocity will be the same as the two original velocities.
"addition and subtraction"Resultant velocity refers to the sum of all vectors in an equation. The two math functions that are used to calculate the resultant velocity are addition and subtraction.
To find the resultant velocity when combining two velocities going in opposite directions, you simply subtract the smaller velocity from the larger velocity. The direction of the resultant velocity will be in the direction of the larger velocity.
The sum of all the velocity vectors.
The sum of all the velocity vectors.
Velocity=displacement(distance)/time.
You can calculate that with the Pythagorean theorem.
When two velocities are in opposite directions, subtract the smaller velocity from the larger one. The direction of the resulting velocity will be in the direction of the larger velocity. This is because the smaller velocity is effectively being subtracted from the larger one.
Resultant velocity is the overall velocity of an object when taking into account both its speed and direction. It is calculated by combining the individual velocities of the object using vector addition. The resultant velocity represents the net effect of all the individual velocities acting on the object.
