[-/9 Points] DETAILS SERCP11 3.2.P.017. MY NOTES ASK YOUR TEACHER A projectile is launched with an initial speed of 44.0 m/s at an angle of 35.00 above the horizontal. The projectile lands on a hillside 3.80 s later. Neglect air friction. (Assume that the +x-axis is to the right and the +y-axis is up along the page.) (a) What is the projectile's velocity at the highest point of its trajectory? magnitude m/s direction counterclockwise from the +x-axis (b) What is the straight-line distance from where the projectile was launched to where it hits its target? m 20. [-/9 Points] DETAILS SERCP11 4.A.P.074. MY NOTES ASK YOUR TEACHER Consider the figure below. (Let w, = 150 N and W2 = 37.0 N.) W2 (a) What is the minimum force of friction required to hold the system of the figure above in equilibrium? N (b) What coefficient of static friction between the 150-N block and the table ensures equilibrium? (Enter the minimum acceptable coefficient of friction.) (c) If the coefficient of kinetic friction between the 150-N block and the table is 0.123, what hanging weight should replace the 37.0-N weight to allow the system to move at a constant speed once it is set in motion?
