Answer :

Onyebuchinnajigo

The initial upward velocity of the ping-pong ball is 5 bounces per second.

The given parameters;

  • final velocity of the ping-pong ball, v = 300 bounces per minute

The bounce rate or velocity  in one second;

[tex]v = \frac{300 \ bounces}{\min} \times \frac{1 \ \min}{60 \ s} \\\\v = \frac{5 \ bounces}{s}[/tex]

If after 60 seconds (1 minute), the bounce rate or velocity of the ping-pong ball is 300 bounces, then initially at 1 seconds, the upward velocity or bounce rate is 5 bounces per second.

Thus, the initial upward velocity of the ping-pong ball is 5 bounces per second.
