Question
Transcribed Image Text:1) A firecracker is fired from rest and its gunpowder delivers a constant upward
acceleration of 8 m/s? for 5 seconds, after which the gunpowder is finished.
g = 10m/s²
a) How fast is the firecracker going once the gunpowder is finished?
b) How high is the firecracker at 5s
c) Find the maximum altitude reached by the firecracker.
d) Find the total time the firecracker is in air
Expert Solution
Step 1
Given information:
The acceleration upward provided by the gun powder (a) = 8 m/s2
The time for which the acceleration is provided (t) = 5 s
Initial velocity of the cracker (u) = 0 m/s
Step by step
