Fig. 8.41 represents the velocity-time graph for a lift in a department store
a) Briefly describe the motion represented by OA AB, BC on the
b) Use the graph to calculate the (1) acceleration of the lift and
the total distance travelled by the lift​

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
