Answer:ok yes
Explanation:yes of course
The kinetic energy should be 1,102.5 joules.
For a vertical spring launcher is attached to the top of a block and a ball is placed in the launcher, the position of the ball will be behind the box
<h3>What will be the position of the ball relative to the spring launcher?</h3>
Generally, the equation for the conservation of momentum principle is mathematically given as
(M+m) V1 = M*V2
Therefore, with the ball moving forward we have that; the ball at top it wii be behind the box,

Answer
given,
mass of the gate = 4.5 kg
distance between the hinge 1.5 m
mass of the bird = 1.1 kg
velocity of the bird = 5 m/s
a) from conservation of angular momentum
b) There is no external torque hence, momentum is conserved
initial kinetic energy =
initial kinetic energy =
= 13.75 J
final kinetic energy
KE =
KE =
KE = 7.14 J
Kinetic energy is not conserved
hence, the collision is inelastic.
The total displacement is equal to the total distance. For the east or E direction, the distance is determined using the equation:
d = vt = (22 m/s)(12 s) = 264 m
For the west or W direction, we use the equations:
a = (v - v₀)/t
d = v₀t + 0.5at²
Because the object slows down, the acceleration is negative. So,
-1.2 m/s² = (0 m/s - 22 m/s)/t
t = 18.33 seconds
d = (22 m/s)(18.33 s) + 0.5(-1.2 m/s²)(18.33 s)²
d = 201.67 m
Thus,
Total Displacement = 264 m + 201.67 m = 465.67 or approximately 4.7×10² m.
