Step 1

It is given that on a strange planet, the maximum horizontal distance covered by an astronaut is R= 16.0 m when he jumps with an initial speed of u=2.60 m/s.

The formula for horizontal distance covered for a projectile motion is given by:

Step 2

For maximum horizontal distance covered, theta = 45o.
