A 60 gm tennis ball thrown vertically up at 24 m/s rises to a maximum height of 26 m. What was the work done by resistive forces?

Explanation

To find the work done by resistive forces on a tennis ball thrown vertically upwards, we can follow these steps:

### Step 1: Convert mass to kilograms
The mass of the tennis ball is given as 60 grams. We need to convert this to kilograms for standard SI units.

\[ \text{Mass} (m) = 60 \text{ gm} = 0.060 \text{ kg} \]
