Question

Stephen can push with 200N of force on a couch. if the couch has a mass of 20 kg, how much acceleration will the couch have? the answers: 4,000 m/s/s, 100 m/s/s, 10 m/s/s, 180 m/s/s.​

Answer 1

Answer:10m/s^2

Explanation: Given force (F) = 200N ,Mass (m) = 20kg acceleration (a) = ?

But F=ma , substituting the values in the expression

200N= 20kg×a. Making a the subject. a= 200N/20kg

a= 10Nkg^-1 = 10m/s^2
