Answer :
The resultant velocity of the golf ball is 18.03 m/s
What is Resultant velocity?
An object's total vector velocity is the sum of its component vector velocities. The scalar product of an object's mass and acceleration vector equals the sum of the vector forces acting on it. If indeed the two objects stick together again after impact, divide the total momentum even by sum of the masses. You will then be given the two objects' resultant velocity as a result. In the aforementioned example, 50 would be divided by the total mass of the masses, which really is 10, yielding a speed of 5 metres per second.
Horizontal velocity= 10 m/s
Vertical velocity= 15 m/s
Resultant velocity= [tex]\sqrt{100+225}[/tex] = [tex]\sqrt{325}[/tex] = 18.03 m/s
