Can someone me with this physics problem? i'd really appreciate any i can get!

560 m

Explanation:

"A projectile is fired at time t = 0.0 s from point 0 at the edge of a cliff, with initial velocity components of v₀ₓ = 30 m/s and v₀ᵧ = 100 m/s.  The projectile rises, and then falls into the sea at point P. The time of flight of the projectile is 25 s.  Assume air resistance is negligible.  What is the height of the cliff?"

Use constant acceleration equation in the y direction.

y = y₀ + v₀ t + ½ gt²

0 = h + (100 m/s) (25 s) + ½ (-9.8 m/s²) (25 s)²

h = 560 m

The height of the cliff is 560 m.

if they have a finite resultant

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
