To use a velocity ball, hold it in your hand and throw it with as much force as possible. The ball is designed to measure the speed of your throw. Make sure to take into account your technique and form when using the velocity ball to get an accurate reading of your throwing speed.
To find the speed of the ball, you can use the formula for momentum: momentum = mass x velocity. Rearrange the formula to find the velocity: velocity = momentum / mass. In this case, velocity = 1300 kg / 15 kg ≈ 86.67 m/s.
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.
To determine the velocity of the ball 0.6 seconds after its release, we need more information such as the initial velocity and acceleration of the ball. You would use the formula: velocity = initial velocity + (acceleration * time).
When the boy catches the ball while standing on roller skates, the boy's velocity decreases to zero as he comes to a stop. The ball's velocity also decreases to zero as it is caught by the boy.
The velocity of the ball is 16 feet/sec when it is thrown upward.
