Question

Космическая ракета стартует с космодрома с ускорением 45м/с². Какой путь она пролетит за 4 секунды?

Answer 1

S=a*t^2/2=45*16/2=360 м

Answer 2

Calculation of the Distance Traveled by a Rocket

To calculate the distance traveled by a rocket with an acceleration of 45 m/s² over a period of 4 seconds, we can use the equation of motion:

distance = initial velocity × time + 0.5 × acceleration × time²

In this case, the initial velocity is assumed to be zero since the rocket starts from rest. Therefore, the equation simplifies to:

distance = 0.5 × acceleration × time²

Substituting the given values:

distance = 0.5 × 45 m/s² × (4 s)²

Simplifying the equation:

distance = 0.5 × 45 m/s² × 16 s²

distance = 360 m

Therefore, the rocket will travel a distance of 360 meters in 4 seconds with an acceleration of 45 m/s².
