Given: The intial position of the ball is 3.4 cm. The final position of the ball is -4.2 cm. The time interval is t = 3 s to t2 = 6.1 s. Step 2 Calculation: The average velocity of the object is equal to the ratio of total displacement and total time taken by the object. Write the expression for the average velocity of the ball. Ax レニ At X2-X1 %3D なー」 Here, v is the average velocity, Ax is the change in position, and At is the time interval. Substitute, all known values in the above expression. -4.2 cm-3.4 cm Vニ 6.1 s-3.0 s -7.6 3.1 =-2.4516 cm/s Thus, the average velocity of the ball is -2.4516 cm/s.

Physics Solve the problem ALGEBRAICALLY. Read the problem carefully. Using pencil on paper, derive the solution(s) ALGEBRAICALLY from first principles. Show all mathematical steps. USE VARIABLES, NO NUMBERS, USE VARIABLES. For example, use: m, t, v, a, L, W, H, AW, and Ao for mass, time, velocity, acceleration, dimensions, atomic wt, density, Avogadro's, respectively. 0 0 0 0 0 0 pre 0 nn 0.2 S 0.4 time (s) 0.6 0.8 10P A small mass moves along a straight line such that its position as a function of time is: s=At^b -Ct^d where A = 5, b=4, C=7, d = 5 and where s is in meters and t is in seconds.

1 / 1|. 100% +| E - Paper Homework (counts as Reading Assignment) Рар Solve the following two problems, showing all work and expressing your answer in the proper units. You do not need to use the rules for significant digits, but the precision of your answer should be comparable to the precision of the quantities given. 1. Note: Koalas tend to fall out of trees. Their skulls have properties that tend to protect them from concussions and other damage, so we can be happy about that. A koala falls 2.6 m from a tree. Calculate its velocity just before hitting the ground (unharmed). Use the sign of the velocity to indicate direction (up or down).
