Question 62

A package on a horizontal test track accelerates from rest to 6.0 m s−16.0\ \mathrm{m\,s^{-1}}6.0 ms−1 in 2.0 s. The resultant force on the package is 240 N.

a.

Calculate the mass of the package.

[2]
b.

A 20 kg load is then added to the package and the resultant force is increased to 360 N. Calculate the new acceleration of the package.
