The motion of a 1-lb block B in a horizontal plane is defined by the relations r
Question:
The motion of a 1-lb block B in a horizontal plane is defined by the relations r = 6 (1 + cos 2πt) and θ = 2πt , where r is expressed in feet, t in seconds, and θ in radians. Determine the radial and transverse components of the force exerted on the block when
(a) t = 0,
(b) t = 0.75 s.

I have done job as Embedded System Engineer for just four months but after it i have decided to open my own lab and to work on projects that i can launch my own product in market. I work on different softwares like Proteus, Mikroc to program Embedded Systems. My basic work is on Embedded Systems. I have skills in Autocad, Proteus, C++, C programming and i love to share these skills to other to enhance my knowledge too.
