Answer:
Acceleration is the rate of change in velocity.
Explanation:
For example if you were riding in a car the change in velocity which is defined as an speed in direction. So if you were in a car and the car went from 30 MPH to 40 MPH the speed of the car has accelerated giving you acceleration.
Answer:
Explanation:
Mass of the kid 23.7 kg.
We need to find the acceleration of the kid,
We know that, Parallel force acted on the kid at an angle is
F = m × g × sinθ (F = ma)
m × a = m × g × sinθ
Now, substitute the given values in the above formula to find acceleration of the kid,
23.7 × a = 232.26 × 0.733
23.7 × a = 170.24
Answer:
5.74s
Explanation:
We can first solve for the initial angular velocity using the following formula
Where is the final angular velocity, is the angular acceleration and is the angular displacement
So for the wheel to get from 22.4 to -22.4 with angular acceleration of -7.8 then the time it takes must be
Answer:MA = 15
Explanation:The mechanical advantage for an inclined plane is MA=l/h or length divided by height. So, plugging these variables into the equation would have it set up like this: MA = 30/2. When 30 is divided by 2 you get your answer for mechanical advantage, which would be 15
Answer: set of rules based on standards and guidelines.
