D.It draws objects together in proportion to their mass
Answer: work of 17.52 J is done
Explanation:
Given that;
Force F = 12 N
distance d = 1.46 m
work W = ?
we know that work done is force F multiple by distance d
so Work W = force F × distance d
we substitute our values
Work done W = 12 × 1.46
W = 17.52 J
Therefore a work of 17.52 J is done
Answer:
8.8 cm
31.422 cm/s
Explanation:
m = Mass of block = 0.6 kg
k = Spring constant = 15 N/m
x = Compression of spring
v = Velocity of block
A = Amplitude
As the energy of the system is conserved we have
Amplitude of the oscillations is 8.8 cm
At x = 0.7 A
Again, as the energy of the system is conserved we have
The block's speed is 31.422 cm/s
