प्रश्न
Solve the following problem.
A man throws a ball to maximum horizontal distance of 80 m. Calculate the maximum height reached.
उत्तर
Given: Rmax = 80 m
To find: Maximum height reached (Hmax)
Formula: Rmax = 4Hmax
Calculation:
From formula,
∴ `"H"_"max" = "R"_"max"/4 = 80/4 =` 20 m
The maximum height reached by the ball is 20 m.
