the shape of a sphere, but it is not uniform inside; so you do not know its moment of inertia. In order to determine the moment of inertia, you decide to roll the pumpkin down an incline that makes an angle θwith the horizontal. The pumpkin starts from rest and rolls without slipping. When it has descended a vertical height H, it has acquired ...

3. A block starting from rest slides down the length of an 18 m plank with a uniform acceleration of 4.0 m/s2. How long does the block take to reach the bottom? Answer: 3.0 sec 4. An airplane initially flying at a speed of 60.0 m/s accelerates at 5.0 m/s2 for 600 meters. What is its velocity after this acceleration? Answer: 98 m/s 5.

of 22.0 N. If 2its acceleration is 1.1 m/s , what is the coefficient of friction between the two surfaces? 8) A 1250 kg car traveling at 60.0 km/h comes to a sudden stop in 35 m. What is the coefficient of friction acting on the brakes?
Find the magnitude of the acceleration. 8. (moderate) This problem is not refering to an object in uniform circular motion, but it deals with motion in two dimensions. The velocity (in m/s) of a particle moving in the x-y plane is given by: v = ( 6.0t – 4.0t 2) i + 8.0 j a. What is the acceleration when t = 3.0 seconds? b.
