Aball is released at the point x=2m on an inclined plane with a nonzero initial velocity. after being released, the ball moves with constant acceleration. the acceleration and initial velocity of the ball are described by one of the following four cases: case 1, a> 0,v0> 0; case 2, a> 0,v0< 0; case 3, a< 0,v0> 0; case 4, a< 0,v0< 0.

What is the freezing point of radiator fluid that is 50% antifreeze by mass? kf for water is 1.86 ∘c/m.

Which change would make the diagram correct?

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
