Question

The figure shows an acceleration-versus-force graph for a 5-g object. What should be the value the first tick-Mari on the vertical scale, as indicated by the arrow in the figure? 100 0.100 200 0.200 The figure shows an acceleration-versus-force graph for three objects pulled by wires. If the mass of object 2 is 36 kg, what are the masses of objects 1 and 3? 12 kg and 90 kg 72 kg and 18 kg 12 kg and 72 kg 90 kg and 12 kg A push of magnitude Pacts on a box of weight W as shown in the figure. The push is directed at an angle theta below the horizontal and the fen remains a rest. The box rests on a horizontal surface that has some friction with the box. The normal force on the box due to the floor is equal to

Explanation / Answer

here,

47)

mass , m = 5 kg

at the tick point

force , F = 0.5 N

accelration , a = F/m

a = 0.5/5 = 0.1 m/s^2

answer is B) 0.100

48)

for m2

m2 = 36 kg

at F = 1 N , a = 1 a1

F/m2 = a

1/36 = a1

for m1

F/m1 = a

1/m1 = 3 * a1

1/m1 = 3/36

m1 = 12 kg

for m3

F/m3 = a

5/m3 = 2/36

m3 = 90 kg

the masses m1 = 12 kg , m3 = 90 kg

the correct option is A) m1 = 12 kg , m3 = 90 kg
