(a) Drawa diagram showing the forces acting on the stone, assuming that air resistance is nepligible. Use your diagram to explain () why the string cannot be herizontal, (i) the direction of the resultant force on the stone and (iii) the effect that the resultant force has on the path of the stone. (b) The mass of the stone is e.15 kg and the length of the string between the stone and the boy's hand is 0.50 m. The peried of retation of the stone is 0.40s. Calculate the tension in the string. (e) The boy now whitls the stune in a vertical circle, but the string breaks when it is horizontal. At this instant, the stone is 1.0m above the ground and rising at a speed of 15 ms.

25) In a movie stunt, a car leaves an inclined ramp with a speed of 32.0 m/s. The car's mass is 1050 kg and its velocity is 29.0 m/s at the peak of its flight. How high in the air (relative to the location where it left the ramp) is the car at the peak of its flight? Assume that there is no air problem can be done using Kinematics too. g although the v = 32 m/s h = ? m = 1050 kg 0.01 lo ribar a and boa pugi oq anoiudover '01
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
In designing amusement park rides, a car of mass 95.7 kg is released from a height 49.6meters and then slides on a friction less surface that becomes a vertical circle of radius 11.6. Whats is the maximum height, the car will not loose contact with the track at the highest point A in the circle? (Please submit your answer to 2 decimals) R
A car rounds a bend in the road that has a radius of 73 m. Rather than being banked inward (toward the centre of the curve), the road is banked outward, at an angle of 15°. The coefficient of static friction between the tires and the road is 0.76. a) Draw a FBD diagram of the car, as viewed from behind. Use a coordinate system that is horizontal/vertical (i.e., not rotated). b) Find the maximum speed that the car can go around the bend without sliding off the road.
Answer Saved Suppose the roller skating woman has a mass of 41.3 kg. Her roller blades have a coefficient of kinetic friction 4g = 0.0306 with respect to the street. She approaches the car, slowing to a speed of v = 6.23 m/s when she touches the car. If the average force she exerts to slow herself down has a magnitude of F = 68.3 N how long does it take for her to come to a stop?
A child of mass m rides on a Ferris wheel as shown in figure (a). The child moves in a vertical circle of radius 12.2 m at a constant speed of 2.75 m/s. a circular path at a constant speed. To yield net force vectors with the same magnitude, the normal force at the bottom must be ---Select-- v that at the top. Categorize Because the speed of the child is constant, we can categorize this problem as one involving a particle (the child) ---Select- v, complicated by the gravitational force acting at all times on the child. Тор , Analyze (Use the following as necessary: not m, and g.) We draw a diagram of forces acting on the child at the bottom of the ride as shown in figure (b). The only forces acting on him are the downward gravitational force F, = mg and the upward force n exerted by the seat. The net upward force on the child that provides his centripetal acceleration has a magnitude Fnet.bottom mg Using the particle in uniform circular motion model, apply Newton's second law to the…

A car of mass m is negotiating a circular turn of radius R and speed v on a banked road with an angle of banking θ. The forces on the car are shown below. Ignore friction in this problem. Draw a free body of the car. Identify and show the radial direction. Pick coordinate axes with x pointing in the radial direction towards the center of the circle and y in the vertical direction. Show the coordinate axes on the free body diagram. Set up Newton’s Laws in the radial and vertical direction. Which force provides the centripetal force? Use the equations in part C to solve for the speed of the car in terms of R, Does the speed depend on the mass of the car? If R=250.0 m, m=750.0 kg, calculate the speed of the car.
Hi here's a question on physics.
In the figure, there is a schematic representation of the route followed by a roller coaster. The vehicle with mass m starts to descend with velocity v after climbing a hill of h height. Then the vehicle continues on its way through the vertical circle of radius R. a-)What is the speed of the vehicle at the top and bottom of the vertical circle? b-)What is the reaction force acting on the vehicle at the lower point of the vertical circle? c-)What is the reaction force acting on the vehicle at the top of the vertical circle? m=120kg V=3m/s h=120m R=25m
An object of mass M is attached to a string. The length of the string is r and has no mass. The objects moves in a vertical circle counterclockwise as shown. When the ball is at point F, the string is horizontal. Point E is at the bottom of the circle and point D is at the top of the circle. Air resistance is negligible. Express all algebraic answers in terms of the given quantities and fundamental constants. = The maximum tension the string can have without breaking is Tmax . Derive an expression for vmax, the maximum speed the ball can have at pointE without breaking the string.
