Answer:
Force = 18N
Explanation:
Force = [ mass ( final velocity - initial velocity ) ] / time taken
using the formula, here mass is 3 kg, final velocity = 45 m/s , initial velocity = 45 m/s , time taken = 2 seconds
Force = [ 3 ( 45 - 33 ) ] / 2
Force = 18N
It’s C
Because C is a reflection which reflects something such as mirror
Hope this helps! •~•
SORRY i forgot but i think its A because the sun has a really strong gravitational pull
sorry and hope it helps
