A0.60-kg object is suspended from the ceiling at the end of a 2.0-m string. when pulled to the side and released, it has a speed of 4.0 m/s at the lowest point of its path. what maximum angle does the string make with the vertical as the object swings up?

ø = 53.7º

Explanation:

The measurement of kinetic energy in an object is calculated based on the object's mass and velocity.

KE=1/2mv²

where m is mass

v is velocity

given data

m=0.60 kg

v=4.0 m/s

So

KE = 1/2 . 0.6 . 4^2  

KE= 4.8 J

All the KE is converted into GPE ("Gravitational potential energy (GPE) - energy stored in an object when moving the object to a height")

4.8  = 0.6 . 9.8 . ∆h

∆h  = 0.816 m

This is the height that the object rises.

cos ø  = (2 – 0.816 ) / 2 = 0.592

ø = 53.7º

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

no

explanation:

no i dont know how to solve this you should probably try to google the answer
