A 4.8‒kg block on a 39° inclined plane is acted on by a horizontal force of 46 N as shown below. The coefficient of kinetic friction between the block and the plane is 0.33. (a) What is the acceleration of the block if it is moving up the plane? (b) With the horizontal force still acting, how far up the plane will the block go if it has an initial speed of 4.3 m/s? (c) What happens to the block after it reaches the highest point? Give an argument to back your answer.
