Answer» ass,= 60 kgCoefficient of STATIC friction,= 0.5Coefficient of Kinetic friction,= 0.4To find:ACCELERATION = ?SOLUTION:Maximum static friction will be:= On putting the values, we get= = Maximum kinetic friction will be:= = then,⇒ or,⇒ On substituting the values, we get⇒ ⇒ Thus, the acceleration will be "0.98 m/s²". |
