Answer:
0.42 m
Explanation:
mass of pendulum, M = 1.7 kg
Length of pendulum , l = 1.6 m
mass of bullet, m = 0.01 kg
initial velocity of bullet, u = 828 m/s
final velocity of bullet, v = 340 m/s
initial velocity of pendulum, U = 0
Let the final velocity of pendulum is V.
Use conservation of momentum for bullet and the pendulum
m x u + M x U = m x v + M x V
0.01 x 828 + 1.7 x 0 = 0.01 x 340 + 1.7 x V
8.28 + 0 = 3.4 = 1.7 V
V = 2.87 m/s
Now the kinetic energy of the pendulum is converted into potential energy of pendulum and let it raised to a height of h from the initial level.
Use energy conservation
Kinetic energy of the pendulum = potential energy of the pendulum
0.5 x M x V² = M x g x h
0.5 x 2.87 x 2.87 = 9.8 x h
h = 0.42 m
Answer:
True
Explanations
Temperature is the degree of coldness or hotness of a body, usually organism rarely adapt to extreme temperature value of below 0°C or above 43°C,organisms usually respond to cold weather by hibernation or estivation for hot weather also extreme temperature causes migration of birds if they can't survive such place like the artic tern that travel thousands of miles,
Answer: Sodim hydroxide have a formula of NaOH . So the elements present in the compound is sodium,oxygen and hydrogen.
Explanation:
The characteristics of the projectile launch allows to find the results for the questions about the movement of the ball are:
-
In the attached we see the vertical speed decreases with height and the curve is of the parabolic type.
- In the movement is several dimensions, each one is independent of the others, the movement in the x axis does not affect the movement in the y axis.
Kinematics studies the motion of bodies looking for relationships between position, velocity and acceleration. In the case of vertical and projectiles launch the acceleration on the vertical axis is the acceleration of gravity directed downward.
In the attachment we can see the position of the ball for two distances in the case of projectile launching.
We can see that the speed of the ball decreases with height according to the relation
y = go t - ½ g t²
Where y is the height, g is the initial vertical velocity, g is the acceleration of gravity and t is time.
In all movements in various dimensions we assume that each movement in an .
axis is independent
In the case of projectile launching, on the vertical axis there is an acceleration of gravity and on the horizontal axis there is no acceleration, the only parameter that this gives the two movements is the time, which is a scalar.
In conclusion, using the characteristics of the projectile launch, we can find the results for the questions about the movement of the ball are:
- In the movement is several dimensions, each one is independent of the others, the movement in the x axis does not affect the movement in the y axis.
- In the attached we see the vertical speed decreases with height and the curve is of the parabolic type.
