Horizontal frictionless floor is pulled with a cord

Reference no: EM13679137

A 3.76 kg block located on a horizontal frictionless floor is pulled with a cord that exerts a force F=10.1 N at an angle = 19.0° above the horizontal, as shown. What is the speed of the block 3.90 seconds after it starts moving?
