In the following example,try to identify the number of times the velocity of the ball changes:
"A football player kicks a football to another player of his team who kicks the football towards the goal. The goalkeeper of the opposite team collects the football and kicks it towards a player of his own team"?
Also identify the agent supplying the force in each case.

Identify the types of forces in each of the following Which type of force is used by a boy to kick a football?

A football player kicks a 0.25 kg ball and imparts it a velocity of 10 m/s. The contact between foot and the ball is only (1)/(50)th of a second. The kicking force is

A football player kicks a 0.41 kg football initially at rest, and the ball flies through the air. If the kicker's foot was in contact with the ball for 0.051 s and the ball's initial speed after the collision is 21 m/s, what was the magnitude of the average force on the football?

A player kicks a football of mass 0.5 kg and the football begins to move with a velocity of 10 m/s . If the contact between the leg and the football lasts for (1)/(50) sec , then the force acted on the football should be

A player in the football team tries to kick a football so that it stays in the air for a long "hang time". If the ball is kicked with an initial velocity of 25.0 m/s at an angle of 60.0^(@) above the ground, what is the "hang time"?

A player stops a football weighing 0.5 kg which comes flying towards him with a velocity of 10m//s . If the impact lasts for 1//50 th sec. and the ball bounces back with a velocity of 15 m//s , then the average force involved is

Study the given information carefully and answer the following questions. There was a football tournament of three teams i.e. A, B and C in which each team played 2 matches. Score pattern of the tournament is: • A team gets 2 points for scoring a goal against the opponent team. • A team gets 3 points for scoring a goal against the opponent team from the outside area. • There is a penalty of 1 point if a team concedes a goal. • Only three players from each team scored the goals. A – B Match: B is the winner of this game. Total points scored by B in this match is 4 . Also, team A scored 2 goals and none of the players scored the goal from the outside area. A – C Match: C scored 0 points in the match. Only one player from team A scored a goal from outside area. A scored 4 points in this match. B – C Match: B gets 6 points from match. Team C scored 1 goal more than Team B. One player from team B scored a goal from outside area but none from team C. What is the maximum possible sum of the total number of goals scored by those players of all three teams, who score more than one goal in a tournament?
