Question #6468

You are watching your friend play hockey. In the course of the game, he strikes the puck in such a way that, when it is at its highest point, it just clears the surrounding 2.88 m high Plexiglas wall that is 13.1 m away. (Ignore any effects due to air resistance.)

(a) Find the vertical component of its initial velocity.

v0y = ______ m/s

(b) Find the time it takes to reach the wall.

Δt = _______-s

(c) Find the horizontal component of its initial velocity, and its initial speed and angle.

v0x = _______m/s

v0 = _______ m/s

θ = _______°

(a) Find the vertical component of its initial velocity.

(b) Find the time it takes to reach the wall.

Δt = _______-s

(c) Find the horizontal component of its initial velocity, and its initial speed and angle.

v0x = _______m/s

v0 = _______ m/s

θ = _______°

Expert's answer

(a) Find the vertical component of its initial velocity.

v0y = 7,51 m/s

&

(b) Find the time it takes to reach the wall.

Δt = 0,77 s

&

(c) Find the horizontal component of its initial velocity, and its initial speed and angle.

v0x = 17,01 m/s

v0 =& 18,59 m/s

θ = 23,82°

v0y = 7,51 m/s

&

(b) Find the time it takes to reach the wall.

Δt = 0,77 s

&

(c) Find the horizontal component of its initial velocity, and its initial speed and angle.

v0x = 17,01 m/s

v0 =& 18,59 m/s

θ = 23,82°
