Answer 2

by level road you mean no angle ?

Answer 3

yes horizontal ground

Answer 4

since power is given by F (force) times V
and the force applied is 800 (to equate the resistance)

we have
800 * v = 24 * 1000
v = 24 * 1000 / 800
v = 30 m/s

Answer 5

but isnt there any acceleration?

Answer 6

maximum speed hence no more acceleration
