Question:The mechanical properties of cobalt may be improved by incorporating fine particles of tungsten carbide (WC). Given tha
t the moduli of elasticity of these materials are, respectively, 200 GPa and 700 GPa, plot modulus of elasticity vs. the volume percent of WC in Co from 0 to 100 vol% using both upper- and lower-bound expressions to form a performance envelope into which the material will fall. Remember that the isostrain case is the upper-bound case and the isostress is the lower-bound case.Mechanical Properties:Mechanical properties help to identify and classify the materials. The most common Mechanical properties are ductility, tenacity, strength, impact resistance, hardness. The mechanical property does not depend on the quantity of the material.

Answer:
Average speed, v = 25 m/s
Explanation:
It is given that,
Distance travelled by the object, d = 50 meters
Time taken, t = 2 seconds
Average speed is defined as the total distance divided by total time taken i.e.
v = 25 m/s
So, the sped of the object is 25 m/s. Hence, this is the required solution.
