Iwas gone for a day and my teacher taught us somthung new and gave me this worksheet and said i have to learn the new material myself! how do i do these problems?

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

The table below shows the acceleration of gravity on different bodies in the solar system. on which body would a 10 kg lamp has the most gravitational potential energy when lifted to a height of 2 m? a. earth b. mars c. neptune d. uranus

You are given a vector a = 125i and an unknown vector b that is perpendicular to a. the cross-product of these two vectors is a × b = 98k. what is the y-component of vector b?
