If the object weighs 60N on Earth, then its mass is 6.12 kilograms.
If it weighs 60N on the moon, then its mass is 36.97 kilograms.
Whatever its mass is in one place, it has the same mass in any other place. Mass doesn't depend on location, but weight does.

Answer:
.a = 849.05 m / s²
Explanation
The centripetal acceleration is
a = v² / r
Linear and angular velocity are related
v = w r
Angular velocity and frequency are related by
w = 2π f
Let's replace
a = w² r
a = 4π² f² r
Let's reduce to the SI system
f = 2.30 rev / s (2π rad / 1 rev) = 14.45 rad / s
.r = 10.3 cm = 0.103 m
Let's calculate
a = 4π² 14.45² 0.103
.a = 849.05 m / s²
We have F = kx or ma = kx where m and k are constants. Therefore, if x is halved, a must be halved too.
Answer:
Explanation:
Using the conservation of energy we have:
Let's solve it for v:
So the speed at the lowest point is 
Now, using the conservation of momentum we have:
Therefore the speed of the block after the collision is
