B) -4
5b=6a+16
9a=7b-20
b=(6/5)a+(16/5)
9a=7((6/5)a+(16/5))-20
9a=(42/5)a+12/5
(3/5)a=12/5
a=4
5b=6(4)+16
5b=24+16
5b=40
b=8
3(4)-2(8)
12-16=-4

A shot putter releases the shot some distance above the level ground with a velocity of 12. 0 m/s, 51. 0∘ above the horizontal.
KIM [24]

A) The x­-component of the shot's acceleration while in flight is; aₓ = 0 m/s²

B) The y-component of the shot's acceleration while in flight is;

a_y = -9.8 m/s²

C) The x­-component of the shot's velocity while in flight is; vₓ = 7.55 m/s

D) The y-component of the shot's velocity while in flight is;

a_y = 9.32 m/s

<h3>Projectile motion</h3>

A) The x-component of the shot's acceleration while in flight?

aₓ = 0 m/s²

B) Since the object is thrown vertically, it means that it is against gravity and as such acceleration due to gravity will be negative,

Thus, the y-component of the shot's acceleration while in flight is;

a_y = -9.8 m/s²

C) The x-component of the shot's velocity at the beginning of its trajectory is; v_x = v cos θ

v_x = 12 cos 51

v_x = 7.55 m/s

D) The y-component of the shot's velocity at the beginning of its trajectory is; v_y = v sin θ

v_y = 12 sin 51

v_y = 9.32 m/s
