Find The Acceleration And Force Acting On A Body Of Mass 4kg Using The Following VT Graph

Find the acceleration and force acting on a body of mass 4kg using the following v-t graph.

Answers:

Acceleration 

a = Slope of v – t graph 

= y – axis / x – axis 

= 10 m/s / 4s = 2.5 m/s

From Newton’s second law 

F = ma 

= 4 × 2.5 = 10 N
