a boy uses a rope to pull a box weighing 300 Newtons across a surface with a constant velocity . The rope makes an angle of 30 degrees with the horizontal, and the tension in the rope is 100 Newtons. What is the coefficient of friction ??

if the displacement of an object, x, is related to velocity, v , according to the relation x=$v, the constant $ is..... a. acceleration b. length c. time d. area

a field goal kicker kicks a football at rest to 30 meters/second, the footballs mass is .5kg, and the time of contact with the football is .025 seconds, what is the force exerted on the football??

a horizontal force of 200 Newtons is applied to a 55 kg cart across a 10 meter surface. If the cart accelerates at 2 meters/second squared, then what is the work done by the force of friction as it acts to retard the motion of the cart ??
