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!

#1

Initial position of clay plate is y1 = 1.10 m

final position of clay plate is y2 = 15 m

time taken t = 1.40 s

acceleration of plate a = -9.8 m/s^2

now we can use kinematics here to find the initial speed

so initial speed of launch is 16.8 m/s

#2

initial speed is given as v1 = 1.40 m/s

distance moved by the person = 38 m

time taken = 7.10 s

now the acceleration can be found by kinematics

so here on inclined plane we know that

so the angle of inclined plane is 6.5 degree

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

the independent variable, or the one that is intentionally manipulated is the speed.
