Question

a 0.5kg model rocket accelerates from 20 m/s [up] to 45 m/s [up] in 0.70 seconds. what is the force acting on the rocket during that time?

science physics

Answer 1

Answer #1

We know that force = mass*acceleration

= m*(v-u)/t

= 0.5kg*(45 m/s -20m/s)/0.70s

= 0.5kg* 25/0.7 m/s^2

= 17.86 N answer
