<h2>
The average force acting on the ball is 1075 N in the direction of travel of ball.</h2>
Explanation:
Force is given by rate of change of momentum.
Mass of soccer ball = 430 g = 0.43 kg
Initial velocity = 0 m/s
Final velocity = 25 m/s
Change in momentum = 0.43 x 25 - 0.43 x 0
Change in momentum = 10.75 kg m/s
Time taken = 0.01 s
Rate of change of momentum = Change in momentum ÷ Time
Rate of change of momentum = 10.75 ÷ 0.01
Rate of change of momentum = 1075 N
Force = 1075 N
The average force acting on the ball is 1075 N in the direction of travel of ball.
The answer is electricity
Answer:
Both the astronauts and photographer have the same displacement
Explanation:
Displacement is the minimum distance between two point. The initial point of both the astronauts and the photographer was Florida and the final point was California. So, the minimum distance for both of the astronauts and the photographer would be the distance between Florida and California would be the same.
Hence, both the astronauts and photographer will have the same displacement.
