Sorry for answering late! The definition of Fusion is <span>the process or result of joining two or more things together to form a single entity. So that means its False :) </span>
Answer:
2.5 ms^-2
Explanation:
acceleration
= (final velocity - initial velocity)/time
= [(40m/s) - (20m/s)]/8s
= (20m/s)/8s
= 5/2 m/s²
= 2.5 m/s²
= 2.5 ms^-2
Answer:
he angular velocity w = 4.19 rad / s
Explanation:
The girl is synchronized with the movement of the rope, therefore we can describe the movement of the girl with the angular velocity
w = θ/t
if we fear 40 jumps and each one is a revolution
θ = 40 2pi = 80π radiation
t = 1 min = 60 s
w = 80π / 60
w = 4.19 rad / s
this must be the same angular velocity of the rope
