One rock weights 5 Newtons the other rock weights 0.5 Newtons. How much more force will be required to accelerate the first rock at the same rate as the second rock?

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Ineed the answer to question 1 , i’m desperate
