Picture the situation where a ball is attached to the end of a string. By whirling the ball with the string,you can make it move around in a horizontal circle at constant speed.(a) What is the net vertical force on the ball? Sketch a free-body diagram of the forces acting on the ballfor some point in its circular orbit.(b) What must be the direction of the ball’s acceleration to keep it moving in a horizontal circle?(c) From your free-body diagram in part (a), determine the net force acting on the ball. Does this agreewith part (b)?

Note: Answer according to the question. I want Free body diagram mandatory otherwise leave it

As shown in the figure below, a small ball (can be considered as a particle) with mass m moves in a circular motion with a constant speed V around the center O in a frictionless horizontal plane. The radius of the circular motion is R. The central acceleration force Fon the ball is provided by a rope through the center O. Now we pull the rope to reduce the radius of the circular motion to R/2. What is the speed of the ball after the radius is reduced to R/2?

An Atwood's machine is a simply two masses connected by a string that runs over a pulley, so that there is a mass on either side of the pulley. If one of the masses is 12.5 kg and the other mass is 9.75 kg, then determine the acceleration of the masses and the tension in the string. For simplicity you can make the usual assumptions about the string and the pulley. Include a force (or free-body) diagram of the situation.

Consider the pic below. Mass 1 is 1Kg, mass 2 is 2Kg, and mass 3 is 10Kg. The coefficient of kinetic friction on the surface is 0.15. Calculate the magnitude of the acceleration for the system.

A football player launches a ball of mass m from the origin (0,0) with an initial speed v, with at an angle a above the horizontal. The ball lands on the ground at (d,0). Neglecting the drag, a) find out the expression of v, in terms of a and d. b) if d=45m, and a=45°, find out the total time of flight. c) Now consider drag force, F=-bv with b=constant, find a formula of the horizontal distance travelled by the ball x with respect to origin when the ball reaches the maximum height yn. Express the answer as a function of a,g,vo,b and m. (F and v are drage force and velocity vectors respectively) BIU Next Type here to search @ 4- W F A+ # 3 E X $ 4₹ R LI E I % 5 + G 6 Y ER MC Ty FB & 7 Σ U 24°C Rain showers a 00 * 8 * ( 9 K FLI 0 Home 11 End + 11 M ENG 01:44 US 16-07-2022 Insert 5 Dele Bac

The curved sides of a track where bicycles race (a velodrome) is angled rather steeply. Sketch a cross-section of a bike at some point along this curve, and beside it make the free body diagram of the bike at that moment. Neglect air resistance, and any forces that go perpendicular to the paper (such as those which go in the direction of the bike's motion).

Tommy is working on a physics problem and asks his friend Sarah to check his work. He is to draw a free body diagram for a man walking to the left and comes up with the following: He reasons, “The man is walking to the left, so the force of friction is acting in the opposite direction. The normal force should be opposite and equal to that of the gravitational force.” Is Tommy correct with his diagram and reasoning? If so, explain. If not, what mistake did he make? Communication throughout the test will also be evaluated on 1) rounding using significant digits, 2) proper use of units, 3) organization and neatness, and 4) showing all work

Two blocks rest on a frictionless surface as shown. The slope part has an angle of 40◦(A) Draw freebody diagrams for both objects.(B) Write out an equation for the acceleration of the lighter block. Leave all unknowns as letters and put in numerical values for all terms that you can.(C) Write out an equation for the acceleration of the heavier block. Leave all unknowns as letters and put in numerical values for all terms that you can.(D) Would it be possible to solve the system of equations you have written in parts (B) and (C) to find the acceleration? (If you have done everything correctly, it will be possible, but this question is asking about the equations you have written out. If you have done something incorrectly, you can get credit for realizing it.) You do not have to solve this system of equations.
