Answer:
Displacement in Y direction is 0.434 m
Explanation:
initial velocity of the puck is 2.35 m/s at -22 degree
so here it is given as
final velocity is given as 6.42 m/s at 50 degree
so we have
now displacement in Y direction is given as

Explanation:
1) Acceleration is defined as the variation of Velocity
in time
:
(1)
A body also has acceleration when it changes its direction.
In this case we have a bus with a velocity of 60m/s to the east, that accelerates in a time 10s. So, we have to find the bus's acceleration:
(2)
(3) This is the bus's accelerration
2) Now we have a car that accelerates to the west in order to reach a speed of
in the same direction, and we have to find the time
it takes to the car to reach that velocity.
Therefore we have to find from (1):
(4)
(5)
Finally:
(6)
