Ametal marble is launched with a speed of v0 = 3.1 m/s at 35° relative to the horizontal, from a height of 1.1 m above ground, and towards a very tall vertical wall, which is 1.6 m away from the launch position. the projectile may first hit the wall, or the ground. find: (a) the highest point (both the x- and the y-coordinates) that the projectile reaches between its launch and the collision; (b) the location of the collision (both the x-and the y-coordinates); (c) the velocity (the magnitude and the angle relative to the horizontal -make a sketch so that it is clear which angle you are reporting) at the moment of the collision. same question, but now assume that the vertical wall is 1.8 m away from the launch position

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
