Answer:
85 ft / 15 ft/s = 5.666666... = 5.7 s
Explanation:
Answer:
0.73 m/s in the forward direction
Explanation:
The caterpillar's velocity relative to the ground is given by:
where
is the velocity of the wagon with respect to the ground
v is the velocity of the caterpillar in the wagon's reference frame
In this situation we have
where the negative sign is due to the fact that the caterpillar is moving backward
Substituting,
0.0000004. since it is 10^-7 (note the negative), you would move thedecimal point 7 places to the left.
Answer:
a) , b) , c) ,
Explanation:
a) The angular motion is obtained by integrating the angular acceleration function twice:
The angular motion when t = 2 s. is:
b) Let be the distance between A and the rotation axis, measured in meters. The magnitude of the angular velocity when t = 2 s. is:
Finally, the magnitude of the velocity is:
c) The angular acceleration of the disk when t = 2 s. is:
Lastly, the normal and tangential components at point A are, respectively:
Oh yeah sweetie I just don’t got to go to
