Answer:
option C
Explanation:
given,
height of the hammer, h = 2 m
acceleration due to gravity of the moon, g = 1.62 m/s²
time taken by the hammer to reach at bottom = ?
initial speed of the hammer, u = 0 m/s
using equation of motion for the time calculation


t² = 2.469
t = 1.57 s ≅ 1.6 s
hence, the time taken by the hammer to reach the bottom is equal to 1.6 s.
The correct answer is option C
All waves are known to undergo reflection or the bouncing off of an obstacle. Most people are very accustomed to the fact that light waves also undergo reflection. The reflection of light waves off of a mirrored surface results in the formation of an image.
Answer:
Net Force Formula: F1+F2+F3...+FN
*(MAKE SURE YOU MAKE NOTE OF THE NEGATIVE FORCES AND SUBTRACT THEM!)*
Explanation:
Top left: 17N+25N+25N-42N= 25N
Top right: 65N+200N-65N-150N-200N= 150N
Bottom left: 189N+123N+284N-96N-188N-312N= 0N
Bottom right: 34N+77N-12N-34N= 65N
I hope this helps! :))
