An airplane flying at 90m/s is accelerated uniformly at the rate of 0.5m/s2 for 10s. What is its final speed? Physics Question. Im desperate for this answer. I think its a two part question but Im not sure. Can someone please guide me through this to the

Very simple, just use the formula V = Vo + at V = 90 + 0.5*10 = 95

During its (constant) acceleration it gains 0.5 m/s of speed every second (0.5 m/s^2) After 10 seconds it's gained 10 times as much speed as it gains each second. 10*(0.5) = 5 All together it gained 5 m/s. It's final speed is 90+5 = 95 m/s
