Answer:
C. The sum of the momentum gained by both pins will equal the amount of momentum lost by the ball.
Explanation:
The law of conservation of momentum states that total momentum before collision must be equal to the total momentum after collision.
Momentum could be transferred from one object to another during collision. When the ball hits the stationary pins, momentum is transferred from the ball to the pins.
Since the collision is elastic, momentum is conserved hence total momentum gained by the pins equals the total momentum lost by the ball.
a diverging lens forms a virtual image which is smaller in size as compared to the object. the image formed by the diverging lens is also erect in nature. the image formed by diverging lens on the same side as the object. so when the object is placed beyond the focal point, an erect, smaller and virtual image is formed before the focal point on the same side as the object
Answer:
Explanation:
Let the hails are coming down with speed "v" and then rebound with the same speed in opposite direction
So here the change in the momentum of the hails is given as
now we know by Newton's 2nd Law
here we have
now plug in all data
Answer:
x = 54.15 meters between the balloons horizontally.
Explanation:
Hence, vertical distance between balloons is 12.8 meters.
y= 61-48.2 = 12.2 m
A right-angle triangle is formed with,
angle θ = 13.3 degrees
opposite (y) = 12.8
adjacent (x) = ?
Now by putting the values in the above equation.
x = 54.15 meters between the balloons horizontally.
Answer:
Explanation:
We can solve the problem by using Hooke's law:
where
F is the force applied to the spring
k is the spring constant
x is the compression/stretching of the spring
For the spring in the problem, we have
F = 28 N
x = 2.2 cm = 0.022 m
Solving for k, we find
