Answer:
The final velocity of 18 kg ball is = 42.09
Explanation:
Mass of first ball = 18 kg
Mass of second ball = 47 kg
Initial velocity of 18 kg ball = 76
Initial velocity of 47 kg ball = 0
Final velocity of 18 kg ball = ??
Final velocity of 18 kg ball is given by the formula
=
Put all the values in above formula we get
= 2 × 18 ×
= 42.09
Thus, the final velocity of 18 kg ball is = 42.09
Answer:
w = 1.976 rpm
Explanation:
For simulate the gravity we will use the centripetal aceleration , so:
where w is the angular aceleration and r the radius.
We know by the question that:
r = 60.5m
= 2.6m/s2
So, Replacing the data, and solving for w, we get:
W = 0.207 rad/s
Finally we change the angular velocity from rad/s to rpm as:
W = 0.207 rad/s = 0.207*60/(2)= 1.976 rpm
