I have this question for my physics homework and I really don't understand it please help me! It's probably a really simple question but I just can't get my head round it!


1. a) at what time does the ball reach its maximum height?
b) calculate the maximum height that the ball reaches?
c) caculate the height from maximum to the ground?
d) Use your answers form c) and b) to caculate the height above the ground that the ball was thrown from?


2. Homework Equations [/b]



3. a) 1 seconds
b) d=s/t

hi lulu234! welcome to pf! :smile:

the graph is velocity against time

you need to use it to draw a graph (or equation) of distance against time …

then you can answer the questions :wink:

how do I do that? :)

you have a graph of velocity against time

your lectures must have told you some information you can get from it :redface:

I don't know how to change velocity to distance :confused:

That is hard to believe. We do not do your work for you here. You need to show some effort, or this thread will likely be deleted.

Sorry I'm 13 and my teacher hasn't shown me how?

Related to Help Motion of a Ball Physics Homework

1. What is the equation for the motion of a ball?

The equation for the motion of a ball is S = ut + 1/2at^2, where S is the displacement, u is the initial velocity, a is the acceleration, and t is the time.

2. How does air resistance affect the motion of a ball?

Air resistance, also known as drag, can slow down the motion of a ball by creating a force in the opposite direction of the ball's motion. This force increases as the ball's speed increases, eventually reaching a point where the force of air resistance is equal to the ball's weight, resulting in a terminal velocity.

3. What is the difference between projectile motion and free fall motion?

Projectile motion is the motion of an object that is thrown or launched into the air, while free fall motion is the motion of an object that is falling due to the force of gravity. The key difference is that projectile motion includes an initial horizontal velocity, while free fall motion does not.

4. How does the mass of a ball affect its motion?

The mass of a ball affects its motion through its inertia, which is the resistance of an object to change its state of motion. A ball with more mass will have more inertia, meaning it will require more force to accelerate or decelerate compared to a ball with less mass.

5. How does the surface of the ball affect its motion?

The surface of a ball can affect its motion in several ways. A rough surface can create more air resistance, slowing down the ball. A smooth surface can reduce air resistance, allowing the ball to travel further. Additionally, the surface can affect the amount of friction between the ball and the surface it is rolling on, which can impact its speed and direction of motion.
