Hello I need help on my physics If you could help on the three questions I Will appreciate it

I will mark brainliest!!

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

To a of 4 x hz is 1. 0. mm nm nm

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
