Answer to Question #6468 in Mechanics | Relativity for TC

Question

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 = _______°

Answer 1

(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°
