Feb 23, 2020 · One other thing to note is that the x-component of a projectile motion almost always has an acceleration of 0, because the x-component does not contribute to the detour. This might be a little confusing, considering what I shared earlier. I thought it will be useful to know.

Apr 26, 2011 · So the acceleration time graph for an object being thrown upwards and then falling back downwards would be a straight horizontal line at the negative 9.81 mark. If you are familiar with Newton's Second Law of Motion, it says that the acceleration is always in the same direction to the resultant force.

Aug 16, 2011 · If the projectile is moving up, the velocity is negative; if it is moving downward, the velocity is positive. The idea of "slowing down" and "speeding up" is kind of vague. The positive/negative sign on the velocity or acceleration doesn't tell you if the object is speeding up or slowing down alone. For example, if you throw a ball upwards, the ...

Sep 26, 2008 · Homework Statement On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 6 iron. The acceleration due to gravity on the moon is 1/6 of its value on earth. Suppose he hits the ball with a speed of 18 m/s at an angle 45 degrees above the horizontal. a) How much...

Oct 16, 2018 · We had a lab on projectile motion and one of the questions was this: Use your Vy versus t graph to determine the y-component of the acceleration of the puck. Should this be equal to the acceleration due to gravity (9.8 m/s)? Explain why it is or why it is not. The acceleration we got from the Vy vs time graph is -1.90m/s^2.

Oct 4, 2009 · 1.Please note that in the following problem the particle has accelerations in both the x- and the y-directions. Therefore the x and y components of velocity keep changing. Initially (at time t = 0) a particle is moving vertically at 5.6 m/s and and horizontally at …

Apr 26, 2011 · A projectile is fired from the origin O at an angle 45 degrees from the horizontal. At the highest point P of its trajectory, determine the radial and transverse components of it's acceleration in terms of the gravitational acceleration g Homework Equations x= vcos45 t y= vsin45 t - 1\2gt 2 The Attempt at a Solution No clue

Mar 11, 2009 · A moderate wind accelerates a pebble over a horizontal xy plane with a constant acceleration a = (6i + 7j)m/s^2 . At time t = 0, the velocity is (3i)m/s . What are the (a) magnitude and (b) angle of its velocity when it has been displaced by 12.0 m parallel to the x axis? i= acceleration in x component , j = acceleration in y component

Jan 29, 2008 · Projectile Motion! Please Help! Homework Statement The acceleration due to gravity can be measured by firing a projectile upward and measuring the time it takes to pass two given points in both directions. The figure below is a plot of height versus time and shows that the time the projectile takes to pass a

Jun 9, 2023 · The maximum elevation was quite simple. I had an equation for elevation vs time. All I had to do was differentiate it and set it to zero. I noticed that this was intuitive because the derivative of elevation would be velocity and since this is projectile motion i.e. constant acceleration, its velocity at the highest point would be zero.
