Answer:
Time, t = 2.5 seconds
Explanation:
Given that,
Net upward force, F = 1000 N
Mass of the object, m = 50 kg
Initial speed, u = 100 m/s
Final speed, v = 150 m/s
We know that the force acting on an object is given by the product of mass and its acceleration. Mathematically, it is given by :
[tex]F=ma\\\\F=m\dfrac{v-u}{t}\\\\t=m\dfrac{v-u}{F}\\\\t=50\times \dfrac{150-100}{1000}\\\\t=2.5\ s[/tex]
So, the time taken by the object is 2.5 seconds.
