PLEASE WRITE DO THIS HAND WRITTEN ONLY AND PLEASE USE BLUE OR BLACK INK VERY VERY CLEARLY, THANK YOU.

1. A 5.0 kg object has a set of three forces acting on it, as shown in the diagram. At t = O, the object is located at the origin and is at rest. 3?.2 N 3] Use Newton's second law to nd the acceleration of the object. Give both the magnitude and the direction {relative to the +3: axis]. b] What is the velocity of the object at t = 150 seconds? Give both the magnitude and the direction [relative to the +1: axis). c} How far is the object from the origin at t = 7.50 seconds? 2. This problem pertains to the diagram on the right. Two dock workers pull a 1500 kg boat. FA = 40.0 N 45.0 X 37.0 FB = 30.0 N a) What is the sum of force A and force B? Give the x and y components, in units of Newtons. b) What is acceleration of the boat? Give the x and y components, in units of m/52. c) What is the magnitude of the boat's acceleration, in units of m/s? d) What is the direction of the boat's acceleration? Give your answer as an angle measured relative to the x axis
