A 2kg object
A 2 Kg object is moving along with the x-axis with a velocity of 4 m/s at t=0. A constant resultant force of 8 N then acts on the object at an angle of 30° for 30 s.
What is the objects velocity and displacement at the end of the 3 s interval?

I have three questions I need assistance on please: 1. To make an object start moving on a surface with friction requires (a) less force than it takes to keep it moving on the surface at constant velocity (b) the same force as to keep it moving on the surface at constant velocity (c) more force than it takes to keep it moving on the surface at constant velocity (d) a force equal to the weight of the object (2)...

5.1.15 Question Help The velocity of an object moving along a line is given by v 2t+4 ft/s on the interval 0sts4. a. Divide the interval [0, 4] into subintervals, [0, 1], [1, 2], [2, 3], and [3, 4]. On each subinterval, assume the object moves at a constant velocity equal to the value ofv evaluated at the midpoint of the subinterval and use these approximations to estimate the displacement of the object on [0, 4].
