Answer:
6.14 s
Explanation:
The time the rocket takes to reach the top is only determined from its vertical motion.
The initial vertical velocity of the rocket is:

where
u = 100 m/s is the initial speed
is the angle of launch
Now we can apply the suvat equation for an object in free-fall:

where
is the vertical velocity at time t
is the acceleration of gravity
The rocket reaches the top when

So by substituting into the equation, we find the time t at which this happens:

I think it is False because as the Gad relajases fuel it doesn’t move as much anymore
Answer:
An X-ray is used to take pictures of your bones. The waves that are used are known as radiation waves.
Answer:
7.5 km/h (2.1 m/s) due east
Explanation:
The average velocity of the person is given by:

where
d is the displacement
t is the time taken
In this problem,
d = 15 km is the displacement
t = 2.0 h is the time elapsed
so the average velocity is

and the direction is the same as the displacement (east).
We can also convert the velocity into SI units (m/s). We have:
d = 15 km = 15,000 m
t = 2.0 h * 3600 s/h = 7200 s
