Complete Question:
The momentum of an object is determined to be 7.2 × 10-3 kg⋅m/s. Express this quantity as provided or use any equivalent unit. (Note: 1 kg = 1000 g).
Answer:
7.2 gm/s.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Given the following data;
Momentum = 7.2 * 10^-3 kgm/s
1 kg = 1000 g
Substituting the unit in kilograms with grams, we have;
Momentum = 7.2 * 10^-3 * 1000 gm/s
<em>Momentum = 7.2 gm/s. </em>
Answer:
The no. of revolutions does the tub turn while it is in motion is = 52.51 revolutions
Explanation:
Given data
= 0
= 5
Time taken = 7 sec
(1). The angular acceleration is given by
We know that from the equation of motion
-------- (1)
(2). The angular acceleration is given by
- 0.357
We know that from the equation of motion
= 35.01 rev ------- (2)
Total no of revolution made by the machine is
17.5 + 35.01
52.51 rev
Therefore the no. of revolutions does the tub turn while it is in motion is = 52.51 rev
