A soccer ball with mass 0.410 kg is initially moving with speed 4.30 m/s. A soccer player kicks the ball, exerting a constant force of magnitude 44.0 N in the same direction as the ball's motion. Over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.70 m/s?
A sled with a mass of 9.50 kg moves in a straight line on a frictionless horizontal surface. At one point in its path, its speed is 2.80 m/s; after it has traveled 2.50 m beyond this point, its speed is 6.50 m/s. Use the work-energy theorem to find the force acting on the sled, assuming that this force is constant and that it acts in the direction of the sled's motion.
A 400g soccer ball is moving through the air at 3.57m/s [64.8°W of N] horizontally at the top of its flight. If at that instant, the soccer ball is struck by a 450g crocket ball moving at 5.46m/s [N], and the soccer ball flies
A soccer player kicks a ball into the air at an angle of 36.0 Degrees above the horizontal. The initial velocity of the ball is +30.0 m/s. 1).How long is the soccer ball in the air 2).What is the horizontal distance traveled by
A soccer player kicks a ball into the air at an angle of 36 degrees above the horizontal with a speed of 30m/s a.How long is the soccer ball in the air? b. What is the horizontal distance traveled by the ball? c. What is the
The soccer goal is 23.05 m in front of a soccer player. She kicks the ball giving it a speed of 17.97 m/s at an angle of 25.83 degrees from the horizontal. If the goalie is standing exactly in front of the net, find the speed of
A soccer ball of mass 550g is at rest on the ground. The soccer ball is kicked with a force of 108N. The player shoes is in contact with the ball for 0.3m. What is KE of the ball? What is the ball's velocity at the moment it loses
During a soccer game a ball (of mass 0.425 kg), which is initially at rest, is kicked by one of the players. The ball moves off at a speed of 26 m/s. Given that the impact lasted for 8.0 ms, what was the average force exerted on
When a soccer ball is kicked with a vertical speed of 25 m/s its height, h metres, after t seconds is given by the equation h=-5t^2+25t a) how long after it is kicked is the soccer ball at a height of 30 m ? b) How long is the
