Answer:
The acceleration is 0.
Explanation:
The formula for acceleration is:
a = (v-u)/t
If v and u are equal, thus it would be 0 when subtracted, and anything divided by 0 is 0.
Answer:
2 m/s and -2 m/s
Explanation:
The object travels with an angle of
60.0°
with the positive direction of the y-axis: this means that it lies either in the 1st quadrant (positive x) or in the 2nd quadrant (negative x).
If it lies in the 1st quadrant, the value of vx (component of v along x direction) is:

If it lies in the 2nd quadrant, the value of vx (component of v along x direction) is:

Yes. If a downward force is created, it will be felt at the end of the rope as well.
Answer:
impulse = force x time
impulse = 1900000 x 0.005 = 9500Ns
Answer:
-0.481 m/s^2
Explanation:
The force equation of this problem is given as:
F - W = ma
where F = upward force holding the clarinet bag
W = downward force (weight of the clarinet)
The mass of the clarinet bag is 3.010 kg, therefore, its weight is:
W = mg
W = 3.010 * 9.8 = 29.498
F = 28.05 N
Therefore:
28.05 - 29.498 = 3.010 * a
-1.448 = 3.010a
=> a = -1.448 / 3.010
a = -0.481 m/s^2
The acceleration of the bag is downward.
