Starting from rest a model rocket accelerates upwards at 24 m/s2. How fast will it be moving after it has traveled 192 meters?
1 answer:
Answer: 96 m/s
Explanation:
Given information
Acceleration of rocket = 24 m/s2
Distance travelled by rocket = 192 meters.
To be calculated
Velocity of rocket at 192 meters = ?
Using 2nd equation of motion, the difference of square of final and initial velocity is equal to the 2 times the product of acceleration and distance.
v2 – u2 = 2as
v2 – 0 = 2 * 24 * 192 (intial velocity is 0, so u = 0)
v2 = 9216
v =
v = 96 m/s
