A spring toy weighing 1 kg on a spring balance suddenly jumps upwards

1.	A spring toy weighing 1 kg on a spring balance suddenly jumps upwards a boy standing near the toy noticesthat the scale of the balance reads 1.05 kg in this process the maximum acceration of the toy is
Answer» Answer: The maximum acceleration of the TOY is 0.5 m/s² Explanation: Mass of the toy m = 1 kg Mass recorded when the toy JUMPS upwards m' = 1.05 kg Similar to the MOTION inside the lifts, when the toy jumps upwards then if the acceleration of the toy is a then NET weight of the toy will be $W'=m(a+g)$ $W'=m(a+g)$ But $W'= m'g$ Therefore, $m(a+g)= m'g$ $\implies 1(a+10)= 1.05\times 10$ $\implies a+10= 10.5$ $\implies a= 10.5-10$ $\implies a= 0.5$ m/s² Thus, the maximum acceleration of the toy is 0.5 m/s² Hope this helps.
