When a soccer ball with a mass of 0.43kg is kicked by a player, the ball can accelerate 25 m/s² off the player's foot. If resisting forces are ignored, such as friction and air resistance, how many Newtons of force did the player use when kicking the ball?

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

Explain the comparisons between nature and packingtown that appears on pages 81 and 82 answer

Ahorizontal force of 400.0 n is required to pull a 1760 n truck across the floor at a constant speed. find the coefficient of sliding friction.
