Question

A cannonball is fired straight up at a speed of 25 m/s. What is the maximum altitude that it will reach?

Answer 1

Answer:

When the projectile is launched straight up, there isn't a horizontal ... The initial acceleration was 9.8 m/s2 pointing up, so the acceleration at any other point should be the same.

Answer 2

The maximum altitude that the cannonball will reach if fired straight up at a speed of 25 m/s is; 31.86 m

According to the question;

The cannonball is fired straight up at a speed of 25 m/s

Additionally, the cannonball is fired against the force of gravity.

Consequently, the motion is in the opposite direction of the acceleration due to gravity.

From the equation of motion;

• V² = U² - 2gH

At the maximum altitude, V = 0.

• 0² = 25² - (2× 9.81) H

• 19.62H = 625

• H = 625/19.62

• H = 31.86m

The maximum altitude that it will reach is;

• H = 31.86m
