rl.bhat said:You are asked to find the change in the velocity, vf - vi. -vi points toward west. So the resultant velocity points towards...?
Change in velocity refers to the difference in an object's speed and direction between two points in time. It can be calculated by subtracting the initial velocity from the final velocity.
To calculate change in velocity, you will need to know the initial velocity (speed and direction) of the object and the final velocity. Then, subtract the initial velocity from the final velocity to find the change in velocity.
The formula for change in velocity is: Δv = vf - vi, where Δv is the change in velocity, vf is the final velocity, and vi is the initial velocity.
Calculating change in velocity for a ball is important because it helps us understand how the ball's speed and direction have changed over time. This can be useful in determining the ball's trajectory and predicting where it will go next.
Yes, change in velocity can be negative. This indicates that the object's speed and direction have decreased between the initial and final points. A negative change in velocity is also known as deceleration or acceleration in the opposite direction.
