Question

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. The shot hits the ground 2. 08 s later. You can ignore air resistance.

Answer 1

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

Projectile motion

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
