PHY1053L: Newton's 2nd Law Pre-laboratory Assignment PHY1053L Pre-laboratory Assignment Lab: Newton's 2nd Law Instruction: Please complete the following pre-lab assignment, upload and submit your work in the lab course blackboard site by the deadline. No late assignment turned in will be accepted. Student Name: Student I.D:. Date: Score (Total 100):. Answer the following questions. Free body diagram: 电 Ym.g mg 1. If a net force of 25.0 N acts on a 6.50 kg object. What is the acceleration of the object? Show your work below m₂

PHY 1053L Newton's 2nd Law Pre-laboratory Assignment p2 2. Suppose that my=0.450 kg block is attached to a mass of my -0.0100 kg as shown in the above figure. Solve for the acceleration a of the system. Show your work below. 3. What is the weight (in N) of a mass of 0.0500 kg? Show your work below. 4. The following table lists the data for the position x versus time t were taken for a block m that is uniformly accelerated. Following the example given below to complete the table. t(s) 0.000 0.100 0.200 0.0102 0.0399 0.300 0.400 0.500 0.0896 0.1603 0.2498 0.600 0.3607 x(m) 0.000 Ax (m) 0.0297 (m/s) 0.297 t(s) 0.050 0.150 0.250 0.350 0.450 0.550 Ar = 0.0399-0.0102= 0.0297 (m): Ar=0.200- 0.100=0.100(*): 0.0297 0.100 -0.297(m/) Example: The velocity calculated in this step is the instantaneous velocity e at the center of At, for example = 0.297 m/s is the instantaneous velocity r at f= 0.150 (the center of 0.100 and 0.200.).

Using the data and the graph paper provided to plot v(as the vertical axis) st(as the borirontal axis), and find the slope(include units) of the best fit to the data. Note: The slope of a striaght line ican be determined by slope = The slope of the best fit in this lab is the acceleration of the block Slope Page 3
