G = 10 N/kg or 10 m/s2
A tennis ball of mass 0.2 kg drops from a height of 20 m. When it hits the ground, it bounces to a height of 14 m.

Describe what happens next
What was the Potential Energy (EP) of the ball before it fell?
What was the efficiency of the bounce?
How fast will Danielle be moving as she reaches the bottom of the hill?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
