Answer:
2.5m/s^2
Explanation:
Since there is no friction, the only force acting on the box is the applied force
We can now use the equation Fnet = ma
and we can rearrange for a
a = Fnet/m
now input the values
a = 50N/20kg
a = 2.5 m/s^2
you may just select the word answer and then without cutting it u may start to type ur answer then it will be in bold letter
