1-aball is tossed from an upper-strory window of building the ball given an in intial velocity8m\s at an angle of 20 below horizontal it strikes the ground 3sec later
a-how far the hoerzintally from the base of the building dies the ball strike the ground
b-find the hight from which the ball was thrown
c-how long does it take the vall to reach apoint 10m below the level of launching
=================================== ===============
2-the speed of projectile when it reaches its miximum height is one half its speed when it is at half its maximum height.what is the intial projection angle of the prijectile
=================================== ================
afirefighter adistance d from aburning building directs a stream of water from water a fire hose at angle intial above the horizontal if intial speed of the stream is Vi at what height h dies the water strike the building
=================================== ==========
asocer player kicks a rock horizontally off a 40m=heigh cliff into pool of water if the player hears the sound of the splash 3sec later what was the intial speed given th the rock assume that the speed of sound in air is 343m\s
