Projectile Motion: Height of hammer thrown downwards

In summary, the person is asking for someone to check their work on a physics question involving a hammer being tossed downward. The question asks how high the hammer would be after 0.75 seconds if it was tossed downward at 4.6 m/s from a height of 9.5 m. The person providing feedback suggests avoiding rounding intermediate values to maintain accuracy in significant figures. They also mention changing the thread title to be more specific.

Hey Guys, I have attempted the question below and need someone to check my work, please.

Thanks!

1. Homework Statement

If the hammer was tossed downward at 4.6 m/s from a height of 9.5 m above ground level, how high would it be after 0.75 s?

Your result turned out okay. However, you should avoid rounding intermediate values to the number of significant figures. Keep a few extra digits in intermediate values, and only round your results at the end. Otherwise, rounding/'truncation errors will creep into your significant figures by the end of the calculations.

I'm changing your thread title to make it more descriptive of the problem being asked. Too-general thread titles, such as "Projectile motion" are not allowed as it is impossible to differentiate one such thread from another by thread title.

1. What is projectile motion?

Projectile motion is the motion of an object that is thrown, launched, or dropped and moves through the air under the force of gravity.

2. How is the height of a hammer thrown downwards calculated?

The height of a hammer thrown downwards can be calculated using the equation h = h0 + v0t + 1/2gt2, where h0 is the initial height, v0 is the initial velocity, t is the time, and g is the acceleration due to gravity.

3. How does the angle of projection affect the height of the hammer?

The angle of projection does not affect the height of the hammer directly. However, it does affect the horizontal distance the hammer travels and the time it takes to reach the ground, which in turn affects the height.

4. What factors can affect the height of a hammer thrown downwards?

The height of a hammer thrown downwards can be affected by the initial velocity, initial height, angle of projection, and air resistance.

5. How does air resistance affect the height of a hammer?

Air resistance can decrease the height of a hammer thrown downwards by slowing down its vertical velocity. This is due to the force of air resistance acting in the opposite direction of the hammer's motion.
