Let us assume that rocket only runs in initial energy and not using its own to flying.
Also , let upward direction is +ve and downward direction is -ve .
Initial velocity , u = 58.8 m/s .
Acceleration due to gravity ,
.
Final velocity , v - = 0 m/s .
We know , by equation of motion .

Hence, this is the required solution .
Answer:
e). 
Explanation:
As we know that wheel is turned by 90 degree angle
so the angular speed of the wheel is given as

now we have


now the centripetal acceleration of the point P is given as



tangential acceleration is given as



now net acceleration is given as



It increases. Mercury takes 88 days to orbit the sun once. The Earth takes a year. Pluto takes 248 years.
Answer:
Increase,.faster
Explanation:
The kinetic energy of the molecules inside the balloon
increases
which means they are moving
faster
I hope this helps you :)
