Catapult vertical displacement problem

Click For Summary
SUMMARY

The discussion revolves around calculating the vertical displacement of a catapult firing at an angle of 40.02 degrees with an initial velocity of 5.463 m/s. The user correctly calculates the vertical component of the initial velocity (voy) as 3.5133 m/s using the formula voy = vo * sin(angle). However, the user encounters an issue with the final displacement calculation, yielding y = 0.62696 meters, which is incorrect. The community emphasizes the need for precise problem statements and detailed calculations to provide accurate assistance.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with trigonometric functions, specifically sine

Homework Statement


A catapult fires at an angle of 40.02 and has an initial velocity of 5.463. Find the vertical displacement at t=.38 seconds.
I know the following from the problem and logic
vo=5.463
t=.3824
g=9.8
angle=40.02
I calcuated the following
voy=vosin40.02
voy=3.5133

Homework Equations


y=(1/2)(-(g))(t^2)+(voy)(t)


The Attempt at a Solution


I know that the value for voy is valid. I plugged them into this equation and got y=.62696 meters. But it isn't the right answer. What do I do?
