Question

a car is moving along a straight road with a uniform acceleration. it passes through two points P and Q separated by a distance with velocity 30km/h and 40km/h respectively the velocity of car midway between P and Q is​

Answer 1

Answer:

25√2 km/hr

Explanation:

Let the distance between them is x

now, using the equation v^2 - u^2 = 2as

we can find acceleration of car which come out to be 350/x km/hr^2

now at the mid point,

v^2 - 30^2 = 2(350/x)x

we get v = 25√2 km/hr
