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...
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...
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
A weight attached to a wire is swung in a circular path. Its speed is 12 meters/sec and it has a centripetal acceleration of 9 meters/sec2. Calculate the diameter of the circle.
__________meters
A rock tied to a string is swung around in a circle with a radius of 10 ft. The centripetal acceleration is 16.9 ft/sec2.
Calculate the speed of the rock.
_____________ft/sec.
A rock tied to a string is swung around in a circle at a constant speed of 25 ft/sec. The length of the string is 1.765 ft. Calculate the acceleration. (Round to nearest whole number.)
acceleration = ________ft/sec2
