A body is moving vertically upwards. Its velocity changes at a constant rate from `50 "m s"^(-1)` to `20 "m s"^(-1)` in 3 s. What is its acceleration ?

Text Solution

AI Generated Solution

To find the acceleration of a body moving vertically upwards with a change in velocity, we can use the formula for acceleration: **Step 1: Identify the given values.** - Initial velocity (u) = 50 m/s (upwards) - Final velocity (v) = 20 m/s (upwards) - Time (t) = 3 s **Step 2: Use the formula for acceleration.** ...
