Question

A force produces an acceleration of 16 m /s2 in a body of mass 0.5 kg and an acceleration of 4.0 m/s2

Answer 1

Answer:

A1= 16 m/s²

m1 = 0.5 kg

force = F = m1a1 = 16 x 0.5 = 8N

same force is applied to the second mass; m2

F = m2a2 = 8N

or

m2 = 8/a2

m2 = 8/4 = 2kg

total mass = m1 + m2 = 0.5 + 2 = 2.5 kg

force is same as before

so,

a = F/M

= 8/ 2.5

= 3.2 m/s²
