A block of mass m1-27 kg initially has a velocity of 14 m/s in the +x direction. It collides with a 2nd block of mass m2- 10 kg, which initially has a velocity of 23 m/s in the +y direction. The two blocks stick together after the collision. What is speed of the combined blocks after the collision? OA) 7.97 m/s OB) 9.97 m/s OC) 12.0 m/s D) 14.0 m/s E) 15.9 m/s
55 N 38 A force of 55 N is applied downward at an angle of 38 degrees with respect to the horizontal on a 5.0 kg block.
