Pe=1/2Kx^2
Half times spring constant times distance squared over time
Momentum
mava + mbvb = mava '+ mbvb'
(300 x 10)+(150 x 0) = (300 x 4.12)+(150 x vb')
3000=1236+150vb'
1764 = 150vb'
vb'=+11.76 m/s ≈ +11.8 m/s (positive sign, to the right)
Answer:
The answer is 50 Nm
Explanation:
<h3><u>Given</u>;</h3>
- Applied Force = 50 Newton
- Total Displacement = 1 meter
<h3>
<u>To </u><u>Find</u>;</h3>
Here,
W = F • d
W = 50 • 1
W = 50 Nm
Thus, Work done is 50 Nm
