1)a clay plate at a shooting range is launched straight up into the air from a device 1.10 m above the ground. after 1.40 s the clay plate is pulverized at a height of 15.0 m. what initial speed was the clay plate launched upward? 2)a person is walking along an icy road. they are able to keep a good walking pace of 1.40 m/s. the road suddenly slopes downward and the person slips down the 38.0 m slope. it takes them 7.10 s to slide all the way down the slope. what is the angle of the slope? , if you could me out with these and also provide explanations, that would be greatly appreciated!
