• 20. Which mass would have the greatest acceleration if the same unbalanced force was applied to each? A) I kg ) 2 kg C) 3 kg D) 4 kg cuis 21. All unbalanced force is applied to a mass, producing an acceleration. If the same unbalanced force is applied to a mass one-half as large, the resulting acceleration will be A the same B twice as great

Draw a separate free-body diagram for each block and find (a) the acceleration of the blocks, (b) the resultant force on each block, and (c) the magnitudes of the contact forces between the blocks. 4) The assembly in the Right Figure is used to calculate the acceleration of a given system.
• Two blocks, of mass 4.0 and 6.0 kg are joined by a string and rest on a frictionless horizontal table. If a force of 100 N is applied horizontally on one of the blocks, find the acceleration of each block and the tension in the string. [a = 10 ms-2, T = 40 N] EXAMPLE Two masses of m = 4.0 kg and M = 6.0 kg are joined together by a string that

6. A 100 kg bag of sand has a weight on 100 N. When dropped its acceleration is what? 7. What is the net force required to give an automobile of mass 1600 kg an acceleration of 4.5 m/s2? 8. What is the acceleration of a wagon of mass 20 kg if a horizontal force of 64 N is applied to it? (ignore friction) 9.
The mass of the reciprocating parts is 250 kg. When the crank has travelled 60° from I.D.C, the difference between the driving and the back pressures is 5. During a trial on steam engine, it is found that the acceleration of the piston is 36 m/s2 when the crank has moved 30° from the inner dead...Mass Acceleration, calculate the net force on the obiect. 9 kg F = mea = 12 kg F mea = a 3 m/s a 4 m/s 5 kg F = mea = 200 kg a = 40 m/s 200 Al a = 6 m/s ) 200 10) Challenge: A student is pushing a 50 kg cart, with a force of 600 N. Another student measures the speed of the cart, and finds that the cart is only accelerating at 3 m/s .
Acceleration = 2 g/7. Explanation: 1) Let the tension in the string connecting 4 g be 'T' and its acceleration be 'a'. Then, Tension in string connecting 12 kg is '2T'. Also, acceleration in string connected to 12 kg is (a+0)/2= a/2. 2) Using Newton's Law, (F = ma) on 4 kg mass. Again on 12 kg mass, 3) Adding above two equations, we get . 5 ...
