<span>The answer to the question is D. To remove the obstacle that's causing frustration. In aggression, one uses hostile behavior to confront an obstacle, often another individual. The behavior is often violent and is used to get rid of the obstacle that is causing the aggressor frustration.</span>
Answer:
(dN)x ,(dN)y= 0
Dn= 0,1.00
Explanation:
Drawing the x and y axis and after that draw the vector of 0.8 north i.e.
+ive y-axis then draw another vector and name it as dW and similarly the third one.
NOw find their resultant that will be from
Dn =0,1.00

The ball is against the vector of gravity. Then, the gravity will be negative.

The ball will stop in the air after approx. 4.72 seconds. And will take the same time to hit the ground.
It will stay approx. 9.44 seconds in the air.
Answer:
Roller coaster will travel 16.07 meter before coming to stop.
Explanation:
We have equation of motion,
, where u is the initial velocity, u is the final velocity, s is the displacement and a is the acceleration.
In this case we have final velocity = 0 m/s, initial velocity = 15 m/s, and acceleration = -7
.

So, roller coaster will travel 16.07 meter before coming to stop.
Answer:
Explanation:
Given
mass of puck=166 gm
initial velocity=19.5 m/s
Final velocity=43.1 m/s at angle of
to the intial direction
Suppose puck is travelling towards positive x axis
thus initial moment 
Final momentum 
Impusle

Angle between initial velocity and force

w.r.t x-axis
and Fdt=Impulse
