Context for question 6

Two particles

P

and

Q

of masses

4 m kg

and

3 m kg

respectively are at rest on smooth horizontal ground.

P

is projected directly towards

Q

with speed

6.5 m/s

. After the particles collide, they move in the same direction and the speeds of

P

and

Q

are

2 m/s

and

v m/s

respectively.

Given that the energy lost in the collision between

P

and

Q

45 J

, find the value of

m

6(b)Motion Graphs Constant AccelerationHard5 marks

After

Q

has moved a distance of

9 m

from the point at which

P

and

Q

first collided, it hits a vertical wall perpendicular to the direction of motion of

Q

and rebounds. The speed of

Q

after hitting the wall is

0.5 m/s

Find the distance from the wall to the point at which the second collision between

P

and

Q

occurs.
