Answer:
10. A boat traveling at 9.5 m/s reduces its acceleration at a rate of 2.5 m/s2. What is the final speed of the boat after it travels 12 meters?
Answer:
b) 2ft/s
Explanation:
A scalar has only magintude, not direction
6.2m, 3kg, and -100 o C are all scalars because they only have magnitude.
2ft/s is not a scalar because it has a direction.
(a) The minimum angle the string can make with the horizontal is 4.4 ⁰.
(b) The rocks speed at the minimum angle is 165.7 m/s.
The given parameters;
- <em>mass of the rock, m = 940 g = 0.94 kg</em>
- <em>length of the string, L = 1.3 m</em>
- <em>Tension on the string, T = 120 N</em>
<em />
The net force on the string is calculated as follows;
The minimum angle the string can make with the horizontal is calculated as follows;
The rocks speed at the minimum angle is calculated as follows;

Gravitation is the power that keeps all magnets in place on earth which maintains rotation and balance.
please vote my answer branliest! Thanks.
Acceleration is a measure of how fast the velocity of a particle/object is changing at a point. Therefore, acceleration can be measured by finding the slope of the velocity of the particle at a certain point.
Since we are given the graph of velocity, we have to find the slope of the particle at point B. In the given graph, the slope of the velocity of the particle at point B is zero. Therefore, the acceleration of the particle at point B is 0.
Hope this helps!
