Answer:

Tangential speed of objects on the planet’s surface = 241 m/s

Explanation:

Speed is given by the ratio of distance traveled to the time.

Radius of mars, r = 3397 km = 3.397 x 10⁶ m

Distance traveled = 2πr = 2 x π x 3.397 x 10⁶ = 2.13 x 10⁷ m

Time taken = 24.6 hours = 24.6 x 60 x 60 = 88560 s

$\texttt{Tangential speed =}\frac{2.13\times 10^7}{88560}=240.51m/s$

Tangential speed of objects on the planet’s surface = 240.51 m/s = 241 m/s
