Question

A standard object defined as having a massof exactly 7.98 kg is given an acceleration of2.5244 m/s2when a certain force is applied toit. A second object of unknown mass acquiresan acceleration of 1.0021 m/s2when the sameforce is applied to it.What is the mass of the second object?Answer in units of kg

Answer 1

Answer:

m' = 20.1024 kg

Explanation:

Given that for standard object

m = 7.98 kg

a= 2.5244 m/s²

From Second law of Newtons

F= m a

Now by putting the values

F = 2.5244 x 7.98 N

F= 20.144 N

In second object

F'= m ' a'

F' = F  ( given that)

20.144 = 1.0021 m'

m' = 20.1024 kg
