Problem

A laboratory cart has a mass of

2.5\times10^{4}\,\text{g}

. It is pulled so that it attains an acceleration of

6.0\times10^{2}\,\text{cm s}^{-2}

. Calculate the force acting on the cart. Express your answer in scientific notation to two significant figures. a)

1.5\times10^{3}\,\text{N}

1.5\times10^{4}\,\text{N}

1.5\times10^{2}\,\text{N}

1.5\times10^{1}\,\text{N}
