An 8 kg mass moving at 8 m/s collides with a 6 kg mass
steposvetlana [31]

Answer:

10 m/s

Explanation:

Momentum before collision = momentum after collision

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(8 kg)(8 m/s) + (6 kg)(6 m/s) = (8 kg)(5 m/s) + (6 kg) v

64 kg m/s + 36 kg m/s = 40 kg m/s + (6 kg) v

60 kg m/s = (6 kg) v

v = 10 m/s

A cyclist rides in a circle with speed 5 m/s. What is his centripetal
Reptile [31]

Answer: 1.32 m/s^2

Explanation:

Centripetal acceleration is given by the formula

a = ( v^2 ) / r

where a is centripetal acceleration, v is velocity and r is radius.

We know that,

v = 5 m/s

r = 19m

Now,

a = ( v^2 ) / r

a = ( 5^2 ) / 19

a = 25 / 19

a = 1.32 m/s^2
