Iknow that this is a lot to ask for but i am really struggling with these and my teacher is sub-par, feel free to assist with as many or as few as you want, i really appreciate it.
a cyclist accelerates down a hill from rest at 1.5 m/s2. assuming the acceleration is uniform, how long is required to reach a velocity of 6 m/s?
a cannon ball is thrown straight down from a tower with an initial velocity of 50 m/s. after 2.0 s, what is its final velocity?
what height will be reached by an arrow shot straight up at an initial velocity of 15 m/s? (ignore air resistance.)
a cyclist, riding at a constant speed of 5.0 m/s, sees a flash of lightning. wanting to get home quickly, she accelerates at 1.0 m/s2 for 4.0 s and then rides at a constant speed for 30.0 s. if she then takes a further 12.0 to slow down uniformly to rest, the total distance traveled after seeing the lightning flash is…?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
