The vertical component is given by the sin of the angle. So this is 20*sin(53)=15.97m/s
The second Newton's law of motion states that the rate of change in momentum of a moving body is proportional to the resultant force.
Therefore, to understand this law one must understand the concept of momentum and that a body in motion experiences force.
As far as momentum is concerned it is important to note that as a body moves the momentum changes with change in time and also that a body at rest has 0 momentum because its speed/velocity is zero.
It is this change in momentum with time that is proportional to the resultant force experienced by the body.
It is Amperes(A), so the answer is A
Mass = momentum / velocity = 4600 / 15 = ..... Kg
Because the forces are not balanced the pin will fall down and go backwards and the force of the bowling ball will keep going after acting upon the non active pin
