Instantaneous Velocity: example problem A train moves slowly eastward along a straight portion of track. 10...
Physics 195 - Straight-line kinematics E. Graph 2: Plot instantaneous velocity as a function of time. NOTE: LEAVE W OF THE LEFT SIDE OF THE GRAPH PAPER FREE IN ORDER TO FIND THE INTERCEPT ON THE TIME AXIS (see diagram below). Rewrite your instantaneous velocity values from column (4) in the table below next to their corresponding time values. Remember that you can treat your average velocity data in column (4) as an instantaneous velocity if you remember that the...
please i need help with this Question 4 10 pts Brian is on Mars and decides to dump his physics textbook into this never before seen hydrocarbon lake. The atmospheric pressure in Mars is 1/4 that of Earth's and the gravitational acceleration is 3m/s^2. The hydrocarbon liquid has a density of 1300 kg/m^3. If the book is experiencing a force of 426 N underneath the lake, how deep is the book inside the lake? The book has a surface area...
