Explanation:
Projectile motion is a form of motion where an object moves in parabolic path (trajectory). Projectile motion only occurs when there is one force applied at the beginning on the trajectory, after which the only interference is from gravity.
The range of an object experiencing projectile motion is given by:
R = u²sin(2θ) / g
where u is the initial velocity, θ is the angle with horizontal and g is the acceleration due to gravity
Given that R = 6.8 m, g = 10 m/s², u = 12 m/s.
R = u²sin(2θ) / g
substituting:
6.8 = 13²sin(2θ) / 10
13²sin(2θ) = 68
sin(2θ) = 0.4024
2θ = sin⁻¹(0.4024)
2θ = 23.73
θ = 11.86°

Explanation:
The acceleration of the system means the acceleration of the centre of mass of the system. So, let's take a quick look at the first two laws of Newton.
Newton's first law states that any object at rest that is not acted upon by outside forces will remain at rest, and that any object in motion not acted upon by outside forces will continue its motion in a straight line at a constant velocity. This laws seems to be at odd with our everyday lives. Let's take a look at the his second law.
Mathematically, the second law can be represented as; F=Ma. The law states that object will accelerate in the direction of the net force.
In order to know the acceleration of attached objects attached to a pulley we need to consider the system of objects as one object, followed by measuring the effect of the net external forces with respect to the ratio of the total mass of the system.
