Answer with Explanation:
We are given that
Differentiate x and y w.r.t t
Substitute t=1
Magnitude of velocity=
Hence, the magnitude of the missile's velocity=16.49 m/s
Substitute t=1
Hence, the magnitude of acceleration when t=1 s=

<h2>Given that,</h2>
Mass of two bumper cars, m₁ = m₂ = 125 kg
Initial speed of car X is, u₁ = 10 m/s
Initial speed of car Z is, u₂ = -12 m/s
Final speed of car Z, v₂ = 10 m/s
We need to find the final speed of car X after the collision. Let v₁ is its final speed. Using the conservation of momentum to find it as follows :
v₁ is the final speed of car X.
So, car X will move with a velocity of -12 m/s.
Answer:
emf will also be 10 times less as compared to when it has fallen
Explanation:
We know, from faraday's law-
and
So, as the height increases the velocity with which it will cross the ring will also increase.
Given
Now, from
From equation a and b we see that velocity when dropped from is 10 times greater when height is 40
so, emf will also be 10 times less as compared to when it has fallen
