A 3.0 kg block start from rest at the top of a 30⁰ incline and slides 2.0 m down the incline in 1.5seconds. Determine the magnitude of the acceleration of the block. The coefficient of kinetic friction between the block and the plane. The frictional force acting on the block The speed of the block after it slides 2.0 m.

A block is sliding along a horizontal surface where the coefficient of kinetic friction is 0.5 between the two. If the block as initial velocity 15.0 m/s, how much time does it take for the block to come to rest?

A micro-transporter moves from one side of an evacuated chamber to another. It is powered by equal-magnitude, opposite-sign charges Q and -Q on top of two station points, as shown in (Figure 1). The transporter's mass is 1.0 g and it is carrying a positive charge of 9.0 x 10-10 C. The figure shows a micro-transporter located between two stations on a horizontal surface. Figure The left station has charge plus upper Q. The right station has charge minus upper Q. The transporter carries positive charge q. The transporter is 6.0 millimeters from the left station and 36.0 millimeters from the right station. +Q Station ( + Station 6.0 mm 36.0 mm

An object is sliding across a frictionless surface at a velocity of 2.40 m/s toward the origin. When it is 6.0 m from the origin, it suddenly experiences an acceleration of -1.60 m / s. If the acceleration remains constant, what will its distance from the origin be when its velocity reaches -12.0 m/s? -80.65 m -37.2 m -40.43 m -16.40 m Next Page Page 6 of 10
