Question

for a particle v-x graph is given find acceleration at x = 3 m​

Answer 1

Answer:

here,

slope of line passing through (2,10)and (4,20) is

(20-10)/(4-2)

=5=dv/dx

equation of line passing through (2,10) is given by

v-10=5(x-2)

v=5x

when x=3

v=15m/s

acceleration is given by

a=v*dv/dx

 =15*5

  =75m/s²

Answer 2

for v-t graph

Explanation:

acceleration from 2 to 4 second is same i.e 5
