Determine the following Answer Choices A. 2.8 m/s^2 B. -2.8 m/s^2 C. 9 m/s D. 9 m/s^2 E. 2.8 m/s 35 F. 5.25 m/s^2 G. 0 m/s 40
D D Question 2 Sliding into home plate during a baseball game can be an effective way to avoid being tagged out. A player running at 6.33 m/s slides a distance of 1.81 m. Assuming her final velocity is zero, calculate the acceleration during this slide. Just give the positive value, even though it is negative, of course. I expect 3 sig figs here. Question 3 1 pts C. 12.94 m A golf ball is dropped and requires a time of 1.32 s to hit the ground. Ignoring air resistance, calculate the distance the golf ball fell. A. 9.78 m B. 8.55 m D. 13.0 m 1 pts
2 Question 4 Find the X component of the vector 14.1m/s [25°S of W]. This is a scalar, so it could be negative. Question 5 What is the sum of the vectors 14 m [20° E of N] and 10 m [225°]? A. 6.5 m, [69 degrees N of W] B. 13.1 m, [20 degrees S of W] C. 17 m [280 degrees] D. 7.1 m [45 degrees W of S] Note that 225 degrees means 45 degrees west of south or south of west. 1 pts 1 pts
