Assessment 5.Topic: Motion in One-DimensionShow your complete solutions. Include necessary diagrams. 5. A lunar lander is making its descent to Moon Base I. The lander descends slowly underthe retro- thrust of its descent engine. The engine is cut off when the lander is 5.0 m abovethe surface and has a downward speed of 0.8 m/s. With the engine off, the lander is in freefall. What is the speed of the lander just before it touches the surface? The acceleration dueto gravity on the moon is 1.6 m/s².

We use the kinematic equation of motion v2=u2+2as to find the final velocity 'v' of the lander.…

The goal of this lab is to draw conclusions about motion graphs and practice graphing motion. mtroduction: Motion graphs are important to understand how objects are moving. In this lab activity, we will create motion graphs from motion diagrams and from description situations. O8 ) = 1 s こ=} as 9 =1 8.

The diagram below shows Harold running from 0m to 100m on the track. He is moving along the positions, shown on the number line and his time at each position is tracked above him. Using these values, first create a data table. Then graph the motion (using time on the x and position on the y). Lor on Ceu 0 10 20 30 40 50 60 70 80 90 100 0 10 S0
