Ya so honestly...I cant figure out how to graph this graph. OK so Willy throws a coin from the top of a cliff. If he throws it with an initial velocity of 22 m.s in the horizontal direction, plot the trajectory of the coin at intervals of 0.10s. How can this be done? Please help me, the more I look at these questions, the more I wonder why in the world did I take this class? Thanks so much for being smart and taking the time to assist me..you are all helping me out more than you even know!
IT can be done by finding the x displacement each .1 second, and the y displacement each .1 second.
You have equations for displacement in x, and y.
These are rather elementary kinematics problems, if you are failing to understand the concepts, maybe you need not to take physics. Or, get a tutor maybe twice a week.
Jee thanks?
On neat way to graph this is put the graph as position (x is horizontal, y is vertical), and put a dot where the ball is each .1 second. Then, the plot will consist of dots, almost like a strobe picture taken over time.
No worries, I'm here to help you out! To graph the trajectory of the coin, we can use the equations of motion.
First, let's break down the problem. The coin is thrown with an initial velocity of 22 m/s in the horizontal direction. This means that the initial velocity in the vertical direction is 0 m/s. The only force acting on the coin is gravity, which causes it to accelerate downward at 9.8 m/s^2.
To plot the trajectory at intervals of 0.10s, we need to calculate the horizontal and vertical positions of the coin at each time interval.
1. Calculate the time interval: Since we want to plot the trajectory at intervals of 0.10s, we start with t = 0s and increment it by 0.10s each time.
2. Calculate the horizontal position (x-axis): The horizontal motion of the coin is constant because there is no horizontal acceleration. So, for each time interval, the horizontal position can be calculated as: x = initial horizontal velocity * time.
3. Calculate the vertical position (y-axis): The vertical position of the coin is affected by gravity and can be determined using the equation: y = initial vertical velocity * time - (1/2) * acceleration due to gravity * time^2.
By plugging in the respective values at each time interval, you can calculate the x and y coordinates of the coin's position. Then, plot these points on a graph with the x-axis representing the horizontal position and the y-axis representing the vertical position.
Repeat this process for each time interval, and you'll have a series of points that represent the trajectory of the coin. Connect these points to visualize the path taken by the coin.
Remember to label your axes and units for clarity. And don't worry, with practice and understanding, you'll be able to tackle these kinds of problems!
