Question

velocity v of a particle decrease linerialy with it's displacement s from 20m/s to a value approaching 0 at s=30m then acceleration of the particle at v=10m/s is​

Answer 1

Explanation:

Slope    dsdv=30−20=3−2

∴ Slope     30−150−v∣∣∣∣∣s=15=3−2            ⟹v∣∣∣∣∣s=15=10m/s

Using       a=vdsdv

∴     a∣∣∣∣∣s=15=v∣∣∣∣∣s=15×dsdv=10×3−2=3−20  m/s2
