Question

A boy running initially at 5 m per second for 5 second after 5 second the speed speed increase to be 10 metre per second . calculate the distance travelled during that acceleration

Answer 1

distance travelled during acceleration is given by newtons equation:

s=ut+1/2at^2

s=5*5+1/2*5*25

s=25+62.5

s=87.5m
