Afootball is kicked and leaves the ground at an angle 37.0° with a velocity of 20.0 ms^-1. calculate the maximum height, the time of travel before the football hits the ground and how far away it hits the ground. assume the ball leaves the foot at ground level, and ignore air resistance and rotation of the ball.

Explanation:

U = 20m/s, theta = 37 degree

The formula for maximum height of a projectile is given by

H = u^2 × Sin^2 theta / 2g

H = 20 × 20 × Sin^2 (37)/ 2 × 9.8

H = 7.35 m

The formula for time of flight is given by

T = 2sin theta / g

T = 2 × 20 × Sin 37/ 9.8

T = 2.45 second

The formula for horizontal range is given by

R = u^2 Sin 2 theta/ g

R = 20 × 20 × Sin 2 × 37/ 9.8

R = 39.24 m

the answer would be c

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
