The outward push of the core created by nuclear fusion and the inward pull of gravity from the core
Answer:
The speed of the chair just before impact is 22.54 m/s
Explanation:
From the question,
The chair was initially at rest, that is, the initial velocity of the chair is 0 m/s.
Since the chair was thrown from a balcony, the chair will fall freely due to gravity.
To determine the speed of the chair just before impact, we will determine the final velocity of the chair.
From one of the equations of linear motion for objects falling freely due to gravity,
v = u + gt
Where v is the final velocity
u is the initial velocity
g is the acceleration due to gravity (Take g = 9.8 m/s²)
and t is time
From the question,
u = 0 m/s
t = 2.3 secs
Then, v = u + gt becomes
v = 0 + (9.8)(2.3)
v = 9.8 × 2.3
v = 22.54 m/s
Hence, the speed of the chair just before impact is 22.54 m/s.
