Answer:
0.08 J
Explanation:
EE = ½ kx²
EE = ½ (400 N/m) (0.02 m)²
EE = 0.08 J
Answer:
power =( 890 N x 12 m ) / 22 s=
= 485 Watts
Explanation:
Answer:
50%
Explanation:
Efficiency = work out / work in
e = Fd / W
e = (2000 N) (2 m) / (8000 J)
e = 0.5
<h3>Answer:</h3>
A. The image is larger than the object and the image is real.
Answer:
Explanation:
initial velocity = 24m/s
final velocity = 0 ( since she is coming to a rest )
time = 12 s
∴ acceleration = final velocity - initial velocity / time
= 0 -24 / 12
= -24/12
= -2 m/s
