Question

A car propelled by water rocket can go from rest to 95 m/s in 2.5s. If it could sustain this acceleration for longer, how far could it travel in 1s of it starts at 95 m/s?

Answer 1

Wouldn’t your answer just be 95 m/s? If it’s starting right off the bat at 95 m/s, wouldn’t your answer be 95 m/s since it’s asking what it starts as in 1 second, after it told you that it propels at 95 m/s?

Answer 2

A car propelled by water rocket can go from rest to 95 m/s in 2.5s. If it could sustain this acceleration for longer, how far could it travel in 1s of it starts at 95 m/s?

kinematic equations

s=ut+1/2at^2

s=95x1+1/2(95/2.4)x1x1

95+95/1.2=>190 just under
