Final answer:
When thrown vertically upwards with an initial speed of 40 m/s, a body can raise approximately 8 meters.
Step-by-step explanation:
In order to find how high a body can raise when thrown vertically upwards with an initial speed of 40 m/s, we can use the equation of motion: velocity^2 = initial velocity^2 + 2 * acceleration * displacement. Rearranging the equation, we get displacement = (velocity^2 - initial velocity^2) / (2 * acceleration). Plugging in the values given, the body can raise approximately 8 meters.
