Question
1) On its own, a tow truck has a maximum
acceleration of 4.53-m/s?.
What will be its maximum acceleration
when the truck is using a light
horizontal chain to tow a bus of 2.4
times its own mass?
âMAX=
2) A net force of 121-N is applied to a
certain object. As a result, the object
accelerates with an acceleration of
21.2-m/52. what is the mass of this object
3) P Flag question
If I weigh 792-N on Earth at a place
where g = 9.80 m/s2 and 5583-N on
the surface of another planet.
What is the acceleration due to gravity
on that planet?
