Answer:
98.12 m
Explanation:
Initial speed(v) = 25.0 m/s
Coefficient of static friction (u) = 0.650
The minimum value of the coefficient of kinetic friction should be the coefficient of static friction.
Kinetic friction is given as
umg = ma (a is the required acceleration)
We then have
a = -ug
= -(0.65*9.8)
= -6.37 m/s^2
The shortest distance d is obtained by
d = (V^2 - v^2)/ 2a
V = 0 m/s (final velocity)
d = (0 - 25^2) / 2(-6.37)
d = -625/-6.37
d = 98.12 m
Answer:
0.06 Nm
Explanation:
mass of object, m = 3 kg
radius of gyration, k = 0.2 m
angular acceleration, α = 0.5 rad/s^2
Moment of inertia of the object
I = 3 x 0.2 x 0.2 = 0.12 kg m^2
The relaton between the torque and teh moment off inertia is
τ = I α
Wheree, τ is torque and α be the angular acceleration and I be the moemnt of inertia
τ = 0.12 x 0.5 = 0.06 Nm
Answer: C.
)in the backyard with bright sunlight
Explanation: its better for the rose plant.
Answer:
It is the force that is present because of the mass of our planet. it's what keeps us stuck on the surface of Earth rather than floating off into space.
