The correct answer is D. 1.55 hm
We need to convert dm to hectometers,
We know that,
1 decimeter = 0.001 hectometers
1 dm = 0.001 hm
Using this conversion we get
(1550 × 1) dm = (1550 × 0.001) hm
1550 dm = 1.55 hm
It means 1550 dm can expressed as 1.55 hectometers.

Something stopped the force and was able to recreate the same amount of force to send it back to her. Example: A pole
Answer:
V_c=5.037 m/s
Explanation:
SOLUTION:
applying the conversation of energy, taking the datum at B
V_b=(m_c+m_b)gh_a=(3+0.5)*9.81*0=0 J
V_b=4.95 m/s
applying the conversation of linear momentum,
(m_c+m_b)V_b=m_c*V_c+m_b*V_b
V_b=6*V_c-34.66 (1)
utilising the relative velocity relation,
V_b/c=V_b-V_c
V_b=0.6-V_c (2)
from (1) (2)
6*V_c-34.66=0.6-V_c
7*V_c=35.26
the final velocity of the cart is
V_c=5.037 m/s
into (2)
V_b=0.6-V_c
V_b=0.6-5.037
= 4.437
