State Newton's second law of motion. (1 mark) A resultant force of 10N acts on a body of mass 0.4kg starting from rest. Find the distance travelled after 10 seconds.

Question

1. State Newton's second law of motion.     
2. A resultant force of 10N acts on a body of mass 0.4kg starting from rest. Find the distance travelled after 10 seconds. 

Answer 1

1. The acceleration of a body is directly proportional to the force applied and inversely proportional to the mass of the body .
2. a=F  =  10m     =25ms⁻²
       M    0.4kg
   s=½at²
     =½×25×10×10
   =1250m
