Problem 1:A baseball of massm=0.155kg is suspended vertically from a tree by a string of lengthL=1.1m and negligible mass. Takezas the upward vertical direction. A short-duration forceF=Fyj+Fzkis applied to the baseball by a bat, momentarily creating a torque about the top of the string

 17%Part (a)Enter an expression for the torque due to the given force about the top of the string, in terms ofm,L,F_y,F_z, and the unit vectorsi,j,k. 

 

 

= LFyi Correct!

 

 

 

 17%Part (b)Calculate the magnitude of the torque, in newton meters, for the forceF= (1.16N)j- (5.6N)k. 

 

 

 

 

 17%Part (c)Find the magnitude of the resulting momentary angular acceleration, in radians per second squared, of the ball about the top of the string. 

 

 

 

 17%Part (e)In order to obtain a torque of= (12Nm)j, what must the value of they-component of the force,F_y, be, in newtons?

Fy=
