yaa i got it now dick thanks for you help

Homework Statement A baseball is hit at ground level. The ball is observed to reach its maximum height above ground level 3.0 s after begin hit. And 2.5 s after reaching this maximum height, the ball is observed to barely clear a fence that is 320 ft from where it was hit. How high is the...

u mean my answer is right??

towards its center

this is my calculation a=Sq root of (at)^2+(ar)^2 at= 5m/s^2 ar=v^2/r= 9/2=4.5 a=sq root(5^2+4.5^2) =6.7 m/s^2 is this is right??

coz that is a constant acceleration?

the two components are ax and ay

Dick, v=3m/s a=5 m/s^2 I guess I can find the magnitude when v=3 m/s . is that right?

Homework Statement A particle moves along a circular path having a radius of 2.0 m. At an instant when the speed of the particle is equal to 3.0 m/s and changing at the rate of 5.0 m/s2, what is the magnitude of the total acceleration of the particle? Homework Equations magitude=...

Question 1: A rifle is aimed horizontally at the center of a large target 60 m away. The initial speed of the bullet is 240 m/s. What is the distance from the center of the target to the point where the bullet strikes the target?

oky, f1=100 x1=20degree and f2 200 x2=30 degree

Homework Statement F1Cosx and F2CosX2 and F1Sinx and F2Sinx2 I need to draw each force vector as an arrow ? how do I do that?

HI , I don't know How to find a angle if the question is arc sin(6/25)+ 90 degree and also arc cos (-.2065) pls help

i think it get calcuate arc tan of Ax/Ay
