Answer:
8.0m/s²
Explanation:
meters per second squared is a unit of acceleration so 8.0m/s² is the answer
Answer:
?do you have a picture of the options orr ?
Explanation:
Gravity.: Gravity is the force that acts at a right angle to the path of an orbiting object.
The ball can't reach the speed of 20 m/s in two seconds, unless you THROW it down from the window with a little bit of initial speed. If you just drop it, then the highest speed it can have after two seconds is 19.6 m/s .
If an object starts from rest and its speed after 2 seconds is 20 m/s, then its acceleration is 20/2 = 10 m/s^2 .
(Gravity on Earth is only 9.8 m/s^2.)
