Question

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 1

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.
