please answer the wuestion with complete solution and explaination

Question I A water jet strikes on a curved surface of a rigid block as shown in Figure Q1. The diameter of the water jet is 45mm and its velocity is 0.80m/s. If the friction on the curved surface is negligible, calculate the magnitude and direction of the reaction force by the block in relation to the water jet. Given the angle, =60 and the jet flow is assumed in a horizontal plane. (10 marks)
