Question
Try this! Hold your right hand out with your palm perpendicular to the ground, as if you were getting ready to shake hands. You can't hold anything in your palm this way because it would fall straight down. Use your left hand to hold a small object, such as a ball or a coin, against your outstretched palm, then let go as you quickly swing your hand to the left across your body, parallel to the ground. You'll find that the object stays against your palm; it doesn’t slip or fall.
Part A Suppose the object's mass is 44 g , with -0.88 and ,-0.33. Determine amin, the minimum acceleration required to keep the object against your palm Express your answer using two significant figures amin m/sExplanation / Answer
Here ,
mass of object , m = 44 gm
m = 0.044 Kg
us = 0.88
uk = 0.33
let the acceleration of the required to object is a
let the normal force is N
N = m * a
for the object to stay at the position
us * N = m * g
us * m * a = m * g
a = 9.8/.88
a = 11.14 m/s^2
the minimum acceleration of the object is 11.14 m/s^2
