Answer:
0.14 J
Explanation:
The maximum velocity is the amplitude times the angular frequency.
vmax = Aω
ω = vmax / A
ω = (3.2 m/s) / (0.06 m)
ω = 53.3 rad/s
For a spring-mass system:
ω = √(k / m)
ω² = k / m
k = ω²m
k = (53.3 rad/s)² (0.050 kg)
k = 142 N/m
The elastic potential energy is:
EE = ½ kx²
EE = ½ (142 N/m) (0.044 m)²
EE = 0.14 J
The answer is option C.
For example, you are being chased by an elephant. The best way to outrun it would be to run in a zig-zag pattern. As the elephant has a large mass,it's mass would be resistant towards moving sideways,thus this proved that greater mass,greater inertia
<span>In Thomson experiment, why was the glowing beam repelled by a negatively charged plate, because the glowing beam was negatively charged. The glowing beam particles were attracted to the positive plate.
</span><span>J.JThomson proved that the cathode rays produced a stream of negatively charged particles called electrons. </span>
