Given:
Distance travelled by the rocket = 16 km
Time = 2 seconds
Acceleration time = 10 seconds
Determine the velocity and acceleration.
Formula for velocity:
v = d/t
v = velocity
d = distance
t = time
Formula for acceleration:
a = change in velocity / change in time.
Solution:
In order to determine the acceleration, we must solve first for the velocity.
v = d/t
v = distance / time
v = 16 km/2 s
v = 8 km/s
Now we' can solve for the acceleration by substituting the values of the velocity and the given time.
a = 8 km/s - 0 km/s / 10s
a = 8 km/s / 10s
a = 0.8 km/s^2
Final answer:
v = 8 km/s
a = 0.8 km/s^2
