Explanation:
It is given that a particle covers 10m in first 5s and 10m in next 3s. so using the equation of motion
Case I
s=ut+

20=10u+25a
4=2u+5a..............(1)
Case 2
In next 3s the particle covers more 10m distance. So
20=8u+

a(8)

5=2u+8a.........(2)
On solving equation (1) and (2)
4=2u+5a
5=2u+8a
a=

Put the value of a in equation (1)
u=

Now to find distance in next 10 s. total time will be 10s
s=

s=28.33m
Distance travelled in next 2 sec
s=28.33−20=8.33m
Answer:
When the rocket's engines are fired up, the force of gravity is disturbed, and the rocket takes off in the air. Later, as the rocket's fuel runs out, it slows down, comes to a halt, and eventually plummets to Earth's surface. Forces can affect objects in space as well. Spaceships are constantly in motion while traversing the solar system.
