What I Have Learned Activity 1.3 Think Critically Solve the following in a clean sheet of paper. Show your solution and box your final answer. 1.) Mark bought a large pizza with a radius of 0.5 m. He unmindfully pours pizza sauce along the pizza edge for a distance of 80 cm. Calculate the angular displacement of the pizza sauce 2.) What is the angular velocity of an object traveling in a circle of radius 0.75 m with a linear speed of 3.5 m/s? 3.) What is the angular acceleration of a ball that starts at rest and increases its angular velocity uniformly to 5 rad/s in 10 s?What I Have Learned Direction. Solve the following problems in a separate paper Show your solutions systematically and clearly A 400 0-N sign hangs from the end of a uniform strut The strut is 4.0 m long and weighs 600.0 N. The strut is supported by a hinge at the wall and by a cable whose other end is tied to the wall at a point 3.0 m above the left end of the strut. Find the tension in the supporting cable and the force of the hinge on the strut GAS A cylinder of mass m and radius R has a moment of inertia of = mr. The cylinder m is released from rest at a height h on an inclined plane, and rolls down the plane without slipping. What is the velocity of the cylinder when it reaches the bottom of the incline? A uniform solid cylinder, sphere, and hoop roll without shipping from rest at the top of an incline. Find out which object would reach the bottom first h
