Question

A particle is moving up an inclined plane . its velocity changes from 15m/s to 10m/s in two seconds . what is acceleration

Answer 1

Answer:

acceleration= -2.5m/s2

in other way retardation= 2.5m/s2

Explanation:

initial velocity(u)=15m/s

final velocity(v)=10m/s

time=2s

acc=v-u/t

=10-15/2

= -5/2

= -2.5

Answer 2

Answer:

initial velocity(u)=15m/s

final velocity(v)=10m/s

time=2s

a=v-u/t

=10-15/2

= -5/2

thus a= -5/2
