A 50-kg ice skater goes around a circle of radius 4 m at a constant speed of 2 m/s on a level ice rink. What are the magnitude and direction of the force that the ice exerts on the skater (the total force, not just the horizontal or vertical component of the force)
Suppose you drive your car and will have to round two curves as shown in the figure. As you approach the curve with a smaller radius, would you a) speed up, b) slow down, or c) maintain your speed, to keep the centripetal force constant? What may possibly happen if the required centripetal force increases? Justify your answer.
Which statement below is incorrect with regard to curved roads? Racetracks have banked turns so cars do not have to slow down too much when navigating them Given several turns of the same radius, made of the same material but at different bank angles, the one which could be navigated at the highest speed would the one with the steepest bank. 4 wheel drive allows one to drive faster around turns in the winter If made of the same material and under the same conditions, a banked curve can always be navigated at a higher speed than a flat curve of the same radius. A banked turn can be navigated safely even if completely covered in ice
A curved road with radius 80m is perfectly banked with an angle of 20º. The designed speed of the road is A) 16.89 m/s B) 285.35 m/s C) 29.12 m/s D) 5.4 m/s B O A ос D
Question 1 (3 points) Listen A 2.00kg mass is swung on the end of a rope that is 1.20m long at a speed of 3.00m/s. What is the centripetal force the rope exerts on the mass? 7.50N 18.0N 15.0N 5.00N Question 2 (2 points) Listen A man pulls a cement block with a force of 450N using a rope that makes an angle of 35.00 above the horizontal. What is the x-component of his pulling force ? 258N
4. A car rounds a banked curve as we will discuss in class on Tuesday. The radius of curvature of the road is R and the banking angle is 0. (a) In the absence of friction, what is the safe speed for the car to take this curve? (b) Now assume the coefficient of friction between the car's tires and the road is lg. Determine the range of speeds the car can have without slipping up or down the road. (c) What is the minimum value of Hs that makes the minimum speed zero? (d) If 0 = 25.0°, for what values of ps can the curve be taken at any speed? Note: The upper limit of Hs you will find is practically impossible to achieve for the car's tires and the road.
A child sitting 1.90 m from the center of a merry-go-round moves with a speed of 2.15 m/s - Calculate the centripetal acceleration of the child. - Calculate the net horizontal force exerted on the child. (mass = 34.5 kg)
The centripetal force acting on a mass in a circular motion is given by F = m*r*w2. What does w stand for? O frequency of rotation O tangential velocity O period of rotation angular velocity
Below are a number of situations involving circular motion. In each case, identify the source of the force needed to keep the objects in question moving in their circular paths. Kinds of forces Normal/friction/gravity(weight) or tension one of these 4 is the answer To (QUESTION C) it’s not centripetal force I am asking for (QUESTION C)
5. A 50 kg object is moving in a circle with a radius of 5 m and a tangential velocity of 5 m/s. Find the centripetal acceleration and centripetal force of this object.
Centripetal Force: I'm trying to understand the forces at work in centripital force, i understand that if an object is moving in a circle then their must be a net inward acceleration. So if centripetal force is what is pushing in on the object toward the center of the circle, then what is pushing outward to counteract this force and hold the object in its rotation? Like a tenis ball on a string, if i swing it and it gain an inward force, then as it swings under that logic it would approach my hand. What is pushing it out?
