Answer: 495.05 m
Explanation:
Given:
Initial velocity of the bullet, u = 1000 m/s, mass of the bullet, m = 10 g, mass of the wooden block, M = 1000 g,
From the swinging of the wooden block just after the collision with the bullet to its maximum height, using conservation law of mechanical energy we have that,
1/2(m+M) = (m+M)gh
Where h = the vertical height of the block in the direction will the block swing, and g = acceleration due to gravity = 10
=> v=
Using the conservation law of linear momentum,
mu = (m+M)v
mu = (m+M) (where v=)
=>h = *
h=
<span>738.3 seconds (12.3 minutes)
If we assume that Joe's speed is 0.6 m/s in the vertical direction, then the total displacement he must cover is 443 meters in the vertical direction. Now, the formula for average speed is:
average speed = total distance / total time
total time = total distance / average speed
total time = 443/0.6
total time = 738.3 seconds</span>
Explanation:
u=40
v=?
h=?
v²-u²=2gs
0²-40²=2×10×s
160=20s
s=160/20
=80m/s
total distance= upward distance ×downward distance
=80+80
=160m
total displacement=0 because u and v is the same.
Answer:
Induced emf is equal to 0.05 volt
Explanation:
We have given length of the solenoid l = 25 cm = 0.25 m
Radius of the solenoid r = 2.3 cm = 0.023 m
Area of the solenoid
Number of turns N = 580
Inductance of the solenoid
Rate of change of current
Induced emf in inductor is equal to
