Answer:
The acceleration of an object is 4 m/s².
Explanation:
The object is thrown from a building 100 meters above the ground, with an initial velocity of 10 meters per second and a flight time of 5 seconds.
It is required to find the acceleration of the object. Let a is the acceleration. Using second equation of kinematics to find it as :
[tex]h=ut+\dfrac{1}{2}at^2\\\\100=10(5)+\dfrac{1}{2}a(5)^2\\\\100=50+\dfrac{1}{2}\times 25a\\\\50=\dfrac{25a}{2}\\\\a=\dfrac{100}{25}=4\ m/s^2[/tex]
So, the acceleration of an object is 4 m/s².
