I had this question
Explanation:
It is given that,
Height, h = 3.1 m
Initial speed of the rocket, u = 0
Final speed of the rocket, v = 28 m/s
(b) Let a is the acceleration of the rocket. Using the formula as :
(a) Let t is the time taken to reach by the rocket to reach to a height of h. So,
t = 0.22 seconds
(c) At t = 0.1 seconds, height of the rocket is given by :
h = 0.63 meters
(d) Let v' is the speed of the rocket 0.10 s after launch.
So,
v' = 12.64 m/s
Hence, this is the required solution.
Answer:
15.68 m/s
Explanation:
Given that,
She catches the ball 3.2 s later at the same height from which it was thrown.
When it reaches the maximum height, its height is equal to 0.
It will move under the action of gravity.
2 here comes for the time of ascent and descent.
So,
So, the initial upward speed of the ball is 15.68 m/s.
