Problem

A force acts on a body in such a way that it increases uniformly from

0

50\,\text{N}

during the first

2\,\text{s}

and then remains constant at

50\,\text{N}

for the next

2\,\text{s}

. What is the magnitude of the impulse delivered to the body in the interval

0

4\,\text{s}

? a)

200\,\text{N\,s}

50\,\text{N\,s}

150\,\text{N\,s}

100\,\text{N\,s}
