A horizontal force, F1 = 95 N, and a force, F2 = 18.9 N acting at an angle of θ to the horizontal, are applied to a block of mass m = 2.9 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right. Calculate the normal force when the angle is 30. and acceleration when the angle is 30.

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
