Just a kinematics question

A particle P is projected vertically upwards from a point on the ground with speed 17m/s
Another particle Q is projected vertically upwards from the same point with speed 7m/s
Particle Q is projected T seconds later than particle P.

Given that the particles reach the ground at the same instant, find the value of T.

Help would be much appreciated

anonymous · Answer

calculate the time required to reach the ground for both P & Q particles using t= 2v/g
thn sutract one from another...u'll get ur answer. 
hope it helps.

oh i got it just equate Time for P to reach ground = time for q to reach ground + Time interval which is T. Thanks, was just really blank after reading the question lol.
