Answer:
a=500/50 = 10 m S2
Explanation:F =m ⋅ a a = F/m a 500/50 = 10 m/S2
hope this help.
<h2>
The balloon is moving when it is halfway down the building at 20.78 m/s.</h2>
Explanation:
We have equation of motion v² = u² + 2as
Initial velocity, u = 0 m/s
Acceleration, a = 9.81 m/s²
Displacement, s = 0.5 x 44 = 22 m
Substituting
v² = u² + 2as
v² = 0² + 2 x 9.81 x 22
v² = 431.64
v = 20.78 m/s
Velocity at 22 m = 20.78 m/s
The balloon is moving when it is halfway down the building at 20.78 m/s.
Answer:
a)
b)
Explanation:
Given:
mass of bullet,
compression of the spring,
force required for the given compression,
(a)
We know
where:
a= acceleration
we have:
initial velocity,
Using the eq. of motion:
where:
v= final velocity after the separation of spring with the bullet.
(b)
Now, in vertical direction we take the above velocity as the initial velocity "u"
so,
∵At maximum height the final velocity will be zero
Using the equation of motion:
where:
h= height
g= acceleration due to gravity
is the height from the release position of the spring.
So, the height from the latched position be:
Kinetic energy = (1/2) (mass) (speed)²
Kinetic energy = (1/2) (6.35 kg) (6.0 m/s)²
Kinetic energy = (3.175 kg) (36 m²/s²)
Kinetic energy = (3.175 · 36) (kg-m²/s²)
1 kg-m²/s² = 1 "Joule"
<em>Kinetic energy = 114.3 Joules</em>
