Answer:
a) 
, b) 
, c) 
, d) 
, e) The direction of the centripetal acceleration experimented by the gum goes to the center of rotation, f) Zero, g) 
.
Explanation:
a) The maximum angular velocity of the fan is:
b) The angular acceleration of the fan is:
c) The magnitude of the tangential aceleration is:
d) The magnitude of the centripetal acceleration is:
e) The direction of the centripetal acceleration experimented by the gum goes to the center of rotation.
f) When fan is at full speed, it rotates at constant rate and, hence, there is no angular acceleration. Besides, the tangential acceleration experimented by the gum is zero.
g) The linear speed of the gum is:
If 1 second = 10000 μs
what about how many seconds = 0.77 μs
the calculations would be done lke this
0.77 x 1/1000000 = 7.7 x 10 ^ -7
Speed = distance / time
distance = length of the spacecraft
therefore speed = 250/7.7 x 10^ -7
ans = 324675324.7 m/s
Answer:
(a) 
(b) 
Explanation:
Given data
Solution
For Part (a)
As the velocity component in direction of y is given by:
The maximum displacement is given by:
For Part (b)
To reach y=46cm =0.46m apply:
Answer:
force-strength,power or energy as an attribute of motion, movement or action. Example: Frictional force.
