Answer:
The launched angle θ = 30 degrees, the initial velocity Vo = 20 m/s, the initial horizontal velocity Vox= ?, the initial vertical velocity Voy = ?, the time of flight t = ? the maximum height h = ?
Vox = Vo * (cos of 30 degrees)
Voy = Vo * (sin of 30 degrees)
t = 2 * (Voy / g)
h = Voy * 0.5 t - 1/2 g * (0.5t)^2
I have given the equations for you to use, just plug – in the values and then solve in a step by step manner.
<h3><u>Question</u> :-</h3>
- What is the mass (in kg) of an object which accelerates at 3 m/s^2 when acted upon by a 15 N force?
<h3><u>Required Solution</u> :-</h3>
- The mass of the object is 5 kg.
<h3><u>Provided tha</u>t :-</h3>
- The force applied on object is 15 N
- The acceleration is 3 m/s²
<h3><u>To Calculate</u> :-</h3>
<h3><u>Using Formula</u> :-</h3>
- Force = Mass × Acceleration
<h3><u>Calculation</u> :-</h3>
Henceforth :-
- The mass of the object is 5 kg.

It is important to follow all directions in the experiment for many reasons such as avoid getting hurt, another reason is if you do not follow all the direction you might make a mistake which could ruin the whole experiment.
Force is used to put things in motion you can’t have motion without force!
Even if it just pushing a piece of paper you still use force to put the paper in motion!
