Answer: (C) The ball will accelerate to about 20 m/s.
Explanation: The ball is in free fall and no other but gravitational force acts on it. This means the ball will be subject to the gravitational acceleration, which is about 9.8 m/s^2. So after one additional second the ball will increase its velocity to (10+9.8) m/s = 19.8 m/s or approx. 20 m/s.
Answer:
1J
Explanation:
Work done = force × distance
1 × 1 = 1
Work done = 1J
J = Joules
The planet Venus is mostly made of atmosphere hope this helps! ^0^
Speed is a scalar quantity, meaning it has no direction. Velocity is a vector, meaning that it has a specific direction associated with it.
Many people use these interchangeably, but it is not always correct to do so.
C is the right answer
