D. is the correct answer forthis question
Answer:
8.05 m/s^2
Explanation:
Instantaneous angular speed(w) = 1.25 rad/s
Angular acceleration (α) = 0.745 rad/s^2
Distance from the centre to where the child is (r) = 4.65m
Tangential acceleration = αr
= 0.745 * 4.65
= 3.464 m/s^2
Centripetal acceleration = w^2r
= (1.25)^2(4.65)
= 7.266 m/s^2
Total acceleration = √3.464^2 + 7.266^2
= √64.794052
= 8.05m/s^2
Answer: Newton
Explanation:-
Force is defined as an interaction that causes an affected object to be pushed or pulled in a certain direction.
where m= mass of an object
a = acceleration of the object
S.I unit of mass is kg and S.I units of acceleration is
Thus For S,I units of force:
Based on scientific data, the stone is accelerated at approximately 10 .
<u>Given the following data:</u>
<h3>What is gravity?</h3>
Gravity can be defined as a force of attraction that controls the movement of the planets such as Earth around the Sun.
This ultimately implies that, gravity is a universal force of attraction that acts between all objects or matter that are having both mass and energy, and can occupy space.
<h3>Gravity on planet Earth</h3>
Furthermore, the gravity near the Earth's surface generally makes it possible for all physical objects such as stones to possess weight and experience a free fall.
According to astronomical records, the acceleration due to gravity for an object experiencing a free fall near the Earth's surface is 9.8 .
In this scenario, the stone is accelerated at approximately 10 .
