Answer:
To decide where the balls land, we need to determine how long the balls are in the air. Both balls will take 2 seconds to hit the ground.
Explanation:
1) Time played forward : gravity & drag forces are in opposite directions so it takes a longer time to reach the ground. 2) Time played backward : gravity & drag forces are in the same direction so it takes a shorter time to reach the ground.
Answer:
Explanation:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces.
Answer:
22/0.50=44
Explanation:
average speed= distance / time
A=f/m
A=900/425
A=2.18
To determine acceleration you divide the force by the mass.
Force = mass x acceleration
Force = 4kg x 10m/s^2
Force = 40N
