A punter kicks the football. The football leaves the punter's foot with a vertical velocity of 20 m/s and a horizontal velocity of 15 m/s.
(a) If the football is allowed to land on the ground, how long is it in the air?
(b) If the football is allowed to land on the ground, what horizontal distance will it travel?
(c) If the football is caught when it is 1 m above the ground, how long will it be in the air?
(d) If caught at 1 m above the ground, what horizontal distance will the football travel?
(e) At what angle did the football travel immediately after being kicked?
Two point charges are placed on the y axis as follows: charge q1= -1.50 nC at y= -.600m, What is the net force (magnitude and DIRECTION) exerted by these two charges on a third charge
A 2kg lunchbox is sent sliding over a frictionless surface, in positive direction of an x axis along the surface. Start at time t = 0, steady wind pushes on the lunchbox in the negative direction of the x axis.
A 1.00x10^2 kg crate is being pushed across a horizontal floor by a force P that makes an angle of 30.0° below the horizontal. The coefficient of kinetic friction is 0.200. What must be the magnitude of P, so that the net work done by it and the k..
