An inclined plane of inclination (&) has a length of 15m. If a body rolls down the plane freely along the entire length with an acceleration 5ms^-2 , calculate the (a) angle &

(b) height of the plane

NB: & = theta

Take g=10m/s²

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?
