Answer 1

Answer:

12 N

Explanation:

Area under v- t graph denotes acceleration

so,

(a) F= ma

= 50 × 10^-3 × area under graph from 6 to 10s

= 50 × 10^-3 × 1/2 × b × h

= 0.05 kg × 0.5 × 4 × 120

= 0.05 × 240

= 12 N

(b) From 3 to 6 s there is no force acting because there is no change in velocity, which implies there is no force
