    How far will the ball travel horizontally?

    Could you please help, I don’t understand this problem. I thought it would rise 20cm because it raises the same height according to Newton’s first law, but that is wrong. could not import diagram. but it is like a half pipe and a ball is on the left side and it is 20 cm from the ground to...

    Relative velocity homework

    An object is thrown directly up (positive direction) with a velocity (vo) of 20 m/s and do= 0. How high does it rise (v = 0 cm/s at top of rise). Remember, acceleration is -9.8 m/s2. d =_______________m this is the problem I was given I think im to use d= do + vot + 1/2atsquared...

    Help dont know where to start

    An object falls because of gravity at a rate of -980 cm/sec2 (- sign is indicative of a downward direction) for 10 seconds. If it starts from rest (vo= 0) and its position starts from do= 0, where is it 10 seconds later? _______________m I don't know where to start
