Answer:
The final velocity of the model rocket after accelerating from rest at 25 m/s² for 3 seconds would be 75 meters per second.
Step-by-step explanation:
You can use the kinematic equation to calculate the final velocity of the rocket when it accelerates from rest at a constant acceleration. The kinematic equation relating initial velocity (u), final velocity (v), acceleration (a), and time (t) is given by:
v = u + at
Where:
v is the final velocity
u is the initial velocity (which is 0 m/s since the rocket starts from rest)
a is the acceleration (25 m/s² in this case)
t is the time (3 seconds)
Plugging in the values:
v = 0 + (25 m/s²) * (3 s)
v = 0 + 75 m/s
v = 75 m/s
So, the final velocity of the model rocket after accelerating from rest at 25 m/s² for 3 seconds would be 75 meters per second.
