Question

A body is moving with a constant acceleration equal to 5 metre per second and from a to b in a straight line ab the velocity of a particle at a and b are 5 metre per second and 15 metre per second respectively the velocity at midpoint of ab is

Answer 1

Answer:

5√5 m/s.... please see explanation

Explanation:

v^2– u^2= 2as

15^2- u^2=2as

2v^2= 5^2+15^2=25+225=250/2= 125

=5√5 m/s
