corrected question:A golf ball is hit with an angle of elevation 60∘ and speed 25ft/s. Find the horizontal and vertical components of the velocity vector. (Your answer must be exact)

Horizontal component=12.5ft/s,  vertical component=21.65ft/s

Explanation:

The bal moves with a velocity of 25ft/s at an angle of 60°.

The horizontal component(Vx) and vertical component(Vy) of velocity can be calculated as follows;

Vx=Vcosθ

Vy=Vsinθ

Vx=25cos60°

=12.5ft/s

Vy=25*sin60°

Vy=21.65ft/s

c) up is the direction the magnetic force is acting on the charge.

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
