<h2>
a) Force would be required to cause the same acceleration on a car of mass 3300 kg is 12229.41 N to the east.</h2><h2>b)
Distance traveled before stopping is 54.45 m
</h2>
Explanation:
a) Force = 8820 N
Mass = 2380 kg
We have
Force = Mass x Acceleration
-8820 = 2380 x a
a = -3.71 m/s²
Now the mass is 3300 kg
Force = Mass x Acceleration
F = 3300 x -3.71 = -12229.41 N
Force would be required to cause the same acceleration on a car of mass 3300 kg is 12229.41 N to the east.
b) We have equation of motion v² = u² + 2as
Initial velocity, u = 20.1 m/s
Acceleration, a = -3.71 m/s²
Final velocity, v = 0 m/s
Substituting
v² = u² + 2as
0² = 20.1² + 2 x -3.71 x s
s = 54.45 m
Distance traveled before stopping is 54.45 m
Some scienist think it was just a rock metal or ice hope i helped :L
Answer:
0.0972644
Explanation:
Wave length = wave speed / frequency
Wave length = 96 / 987
= 0.0972644
Answer: In the 5th dimension, they who claim to know, say that there is only one time, including the past and the future.
Answer:
a = 129.663
Explanation:
We know that:
T = Ia
Where T is the torque, I is the moment of inertia and a is the angular aceleration:
First, we will find the moment of inertia using the following equation:
I =
Where M is the mass and R is the radius of the disk. Replacing values, we get:
I =
I = 0.904 kg*m^2
Second, we will find the torque using the following equation:
T = ()*(R)
Where is the force on one side and is the force on the other side. Replacing values, we get:
T = (162N-63N)(1.184m)
T = 117.216N*m
Finally, we replace T and I on the initial equation as:
T = Ia
117.216N = (0.904)(a)
Solving for a:
a = 129.663
