1. A rocket is launched straight up into the air. If its entire flight takes 5 seconds A) What is the initial velocity of the rocket?
Om/s
B) What is the maximum height the rocket reaches?

1)49m/s

2)122.5m

Explanation:

The expression below can be use to calculate the initial velocity from law of motion

V2 - V1= at

Where V2= final velocity

V1= initial velocity( from rest)

a=acceleration

t= time= 5 seconds

But V2=0

V1=gt

Where g= acceleration due to gravity= 9.8m/s^2

V1= 9.8×5

V1=49m/s

Then we can now calculate the maximum height the rocket reaches by using below formula

V^2=2gh

h(max)=v^2/2g

Where h= maximum height

V2= initial velocity

=49^2/(2×9.8)

=2401/19.6

=122.5m

Hence the maximum height it reaches vis 122.5m

connect the batteries in series and hope

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
