I think the answer is B coz whenever object is in unbalanced it moves
The drag force on that same soccer ball when it is moving through the air at is 7.2 Newton.
Given the data in the question;
- Initial speed;
- Initial drag force;
- Final speed;
Final drag force;
From Newton's laws, Drag force is directly proportional to velocity squared:
Where k is the constant of proportionality.
Hence;
We make "" the subject of the formula
We substitute our values into the equation;
Therefore, the drag force on that same soccer ball when it is moving through the air at is 7.2 Newton.

Answer:
The answer is below
Explanation:
The average velocity is the ratio of total distance traveled to the total time taken to complete the distance. The International System of Units (SI) unit of velocity is the meter per second (m/s). The Velocity is given by the equation:
Velocity = total distance traveled / total time taken
The total distance traveled = Distance traveled by horse + distance traveled by truck + remaining distance traveled = 100 m + 500 m + 1000 m = 1600 m
Total time taken = 120 s
Velocity = total distance traveled / total time taken = 1600 m / 120 s = 13.33 m/s
Velocity = 13.33 m/s

Answer:
3311N
Explanation:
r = radius = 600m
V = speed = 150m/s
Mass = weight = 70kg
The weight of pilot when calculated due to circular motion
W = tv
Fv = mv²/r
Fv = 70x150²/600
Fv = 79x22500/600
= 15750000/600
= 2625N
Real Weight of the pilot = m x g
= 70 x 9.8
= 686N
The apparent Weight is calculated by
Mv²/r + mg
= 2625N + 686N
= 3311 N
Therefore the apparent Weight is 3311N
