CONCEPTUAL Physics-NEXT-TIME QUESTION6).A marble rolling on a horizontal surface encounters an incline and rolls upit without skidding until it comes to a stop. Then it rolls back downagain, also without skidding. The force on the marble due to itsinteraction with the incline has two components-one perpendicular to theincline (the normal force) and one parallel to the incline (a frictionalforce). The frictional force on the marble is directeddown the incline for the upward rolland up the incline for the downward roll.b) up the incline for the upward roll anddown the incline for the downward roll.up the incline for the entire trip.down the incline for the entire trip.c)d)Consider sliding on aslippery slope vs rolling!

Winter is ending. Two penguins, Wheezy and Mumble, are racing down a formerly icy slope into the water below. They have the same mass. The slope is angled at eight degrees to the horizontal. They both start from the same position at the same time, and move downhill entirely due to gravity alone. There is a coefficient of static friction of 0.12 between the penguins and the ground. This time, since they can't slide down the ice, they try rolling all the way down. Wheezy is tumbling sideways and resembles a cylinder (of radius 10 cm) rolling down hill. Mumble tumbles down as if doing somersaults and resembles a sphere (of radius 20 cm) rolling down hill. Who wins the race and what is the winner's acceleration?

Five hockey pucks are sliding across frictionless ice. The drawing shows a top view of the pucks and the three forces that act on each one. The forces can have different magnitudes (F, 2F, or 3F), and can be applied at different points on the puck. Only one of the five pucks could be in equilibrium. Which one?
A spherical bowling ball with mass m = 3.2 kg and radius R = 0.108 m is thrown down the lane with an initial speed of v = 8.7 m/s. The coefficient of kinetic friction between the sliding ball and the ground is μ = 0.26. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) How long does it take the bowling ball to begin rolling without slipping? 2) How far does the bowling ball slide before it begins to roll without slipping? 3) What is the magnitude of the final velocity?

When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total gravitational force on the body, Fg, is supported by the force n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and ? when Fg = n = 720 N. (For ?, enter the smaller of the two possible values between 0° and 90°.) T should be in the 1700-1800 range, please be careful and not give a wrong answer, thanks :)
A car traveling on a flat (unbanked), circular track accelerates uniformly from rest with a tangential acceleration of 1.75 m/s. The car makes it one quarter of the way around the circle before it skids off the track. From these data, determine the coefficient of static friction between the car and track. 0.56 You appear to have forgotten that the static force of friction is also responsible for the tangential acceleration of the car.
