What is reads a larger force pushing upwards (normal force)?
Describe the motion of the following graph:
A flat line on a velocity vs time graph above the x-axis
What is having a positive constant speed/velocity?
A ball is thrown straight upwards with an initial velocity of 22 m/s. It reaches a height of 43 m above the ground then makes its return back to the thrower's hand. What is the velocity of the ball right before it reaches the thrower's hand?
What is -22 m/s?
