Explanation:
Note that from Newton's law of motion:
the sum of the positive horizontal forces on an object equals the sum of the negative horizontal forces therefore, the net force on the object is zero.
Also, velocity is constant, acceleration is zero.
F = m × a
= 0 N
We Know, F = m*a
Here, F = 10 N
m = 1 Kg
Substitute their values in the equation,
10 = 1 * a
a = 10/1
a = 10
So, your final answer & the acceleration of the object would be 10 m/s²
Hope this helps!
As v becomes zero at the highest point, i prefer considering different travelling directions so it will become less complicated.
dont forget to add the total time up .
also to master the skills, write down the "uvsat" may help (thats the way i found it easier to handle problems)
pushing on something that pushes back = action and reaction.
Gravity is non contact. Action at a distance. Hence stones wil fall if dropped.
