Answer:
4.24m/s
Explanation:
Potential energy at the top= kinetic energy at the button
But kinetic energy= sum of linear and rotational kinetic energy of the hoop
PE= mgh
KE= 1/2 mv^2
RE= 1/2 I ω^2
Where
m= mass of the hoop
v= linear velocity
g= acceleration due to gravity
h= height
I= moment of inertia
ω= angular velocity of the hoop.
But
I = m r^2 for hoop and ω = v/r
giving
m g h = 1/2 m v^2 + 1/2 (m r^2) (v^2/r^2) = 1/2 m v^2 + 1/2 m v^2 = m v^2
and m's cancel
g h = v^2
Hence
v= √gh
v= √10×1.8
v= 4.24m/s
Answer:
convergent
Explanation:
Convergent limits are the type of boundary defined by the movement of the plates in the direction of approach, that is, when two tectonic plates move in a convergent direction, colliding between them frontally. In these cases, the dense plate dips under the lightest one, being incorporated into the warm material and fluid of the mantle.
A tsunami can be generated when the boundaries of converging tectonic plates move. For this reason, we can conclude that the type of board boundary that is close to the area that Marina has been studying is a convergent limite.
Mario's velocity vector relative to the ice is

(note that all velocities mentioned here are given in m/s)
The puck is moving in a direction of 17.8 degrees west of south, or 252.2 degrees counterclockwise relative to east. Its velocity vector relative to the ice is then

The velocity of the puch relative to Mario is


Then, relative to Mario,
a. the puck is traveling at a speed of
, and
b. is moving in a direction
such that

which is about
west of south.
