Calculate the kinetic energy of a 4kg cat running 5m/s

Physics
1 answer:
natulia [17]4 years ago
5 0

Kinetic energy  =  (1/2) (mass) (speed)²

                         = (1/2) x (4 kg) x (5 m/s)²

                         =      (2 kg) x (25 m²/s²)

                         =    50 kg-m²/s²  =  <em>50 joules

A horizontal uniform bar of mass 2.7 kg and length 3.0 m is hung horizontally on two vertical strings. String 1 is attached to t
Jlenok [28]

Answer:

14.36 N

Explanation:

T_{1} = Tension in string 1

T_{2} = Tension in string 2

m_b = mass of the bar = 2.7 kg

W_b = weight of the bar

weight of the bar is given as

W_b = m_{b} g = (2.7) (9.8) = 26.46N

m_m = mass of the bar = 1.35 kg

W_m = weight of the monkey

weight of the monkey is given as

W_m = m_{m} g = (1.35) (9.8) = 13.23N

Using equilibrium of torque about left end

W_{m} (AB) + W_{b} (AB) = T_{2} (AC)\\W_{m} (AB) + W_{b} (AB) = T_{2} (AD - CD)\\(13.23) (1.5) + (26.46)(1.5) = T_{2} (3 - 0.65)\\\\T_{2} = 25.33 N

Using equilibrium of force in vertical direction

T_{1} + T_{2} = W_{b} + W_{m}\\T_{1} + 25.33 = 26.46 + 13.23\\T_{1} = 14.36 N

Does water expand more as the temperature drops even more below 0 deg? I am worried about the coolant in my rad. as the temp.is
alex41 [277]
Water is, indeed, an exception. Normally when temperature drops, material shrinks. Water doesn't, water expands instead.

In which situation is the acceleration of the car negative?
VikaD [51]
When a car is slowing down, it has a negative acceleration.  Although it is not going a negative speed, it is decreasing in velocity, which is the definition of a negative acceleration.

Hope this helps!
