A pistol that fires a signal flare gives it an initial velocity (muzzle velocity) of 173 m/s at an angle of 61.0 ∘ above the horizontal. You can ignore air resistance. A. Find the flare's maximum height if it is fired on the level salt flats of Utah.
B. Find the distance from its firing point to its landing point if it is fired on the level salt flats of Utah.
C. Find the flare's maximum height if it is fired over the flat Sea of Tranquility on the Moon, where g=1.62m/s2.
D. Find the distance from its firing point to its landing point if it is fired over the flat Sea of Tranquility on the Moon, where g=1.62m/s2.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

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

inverse v=i*r
