Consider a object of 5 kilos which is fixed with 4 rolling tyres (like in a trolly) which is in a slanting position of 30 degree angle. My questionow to find the force required to move the object upwards the slope along with rolling resistance considered? I tried the force using the F push formula for slope & i tried the coeffiecient for friction of tyres as 0.001 F push= mgsin(theta) + coeff of friction*mgsin(theta) F push=5 * 9.8 *sin(30) + 0.001 * 5*9.8 * cos(30) F push=25.542 Newton Is this correct??? I researched this problem in google, but since the above problem deals with Rolling friction as its attached with tyres, what is the correct method to find the exact force!!! I s it the correct method to find the object moving up the slope with tyres ?
