Question

A particle moving along a straight line with uniform acceleration has velocities 7m/s at p and 17m/s at q. R is the mid point of pq

Answer 1

Answer:

answer should be 12 m/s

Explanation:

let consider the initial velocitybis 7m/s

final is of 17m/s then due to linear accln the velocity at mean of path should me mean of these two given velocities

hence the velocity at R should be 12m/s
