Question

bllow a path along H. then the ball will curve a little bit and then follow a path alongA 27. An astronaut on the moon pushes with an equal force of 20N on a 3kg on a 6kg moon rocks, respectively Which of the following statement(s) is (are) true? a. The acceleration of the 3kg rock is twice that of the 6kg rock b. The 6kg rock pushes back on the astronaut twice as hard as the 3kg rock Since both rocks are on the moon, they will have the same acceleration @Both the rocks will push back at the astronaut with 20N 28. Point P in the fioure indinnton ut

Explanation / Answer

According to newton's third law,

For every action, there is an equal and opposite reaction.

The astronaut exerts the equal force of 20 N on both the rocks, so both the rocks will push the astonaut back with

20 N.

Acceleration a = F / m

a1 = 20 / 3 = 6.66 m/s^2

a2 = 20 / 6 = 3.33 m/s^2

so, acceleration of 3 kg rock is twice that of the 6 kg rck.

option (a) and (d) are correct.
