A ball whose mass is 0.4 kg hits the floor with a speed of 8 m/s and rebounds upward with a speed of 6 m/s. Collapse question pa
Colt1911 [192]

Answer:

The  the average magnitude of the force exerted on the ball by the floor 11.2 \times 10^{3} N

Explanation:

Given:

Mass of ball m = 0.4 kg

Initial speed v_{i} = -8 \frac{m}{s}

Rebound speed v_{f} = 6 \frac{m}{s}

Contact time interval \Delta t = 0.5 \times 10^{-3} sec

For finding the average magnitude of the force on the ball by the floor is given by,

   F_{avg}  = \frac{\Delta P}{\Delta t}

Here \Delta P = m (v_{f}- v_{i} )

   F_{avg} = \frac{m (v_{f} -v_{i}  )}{\Delta t}

   F_{avg} = \frac{0.4 \times (6 -( -8 ) )}{0.5 \times 10^{-3} }

   F_{avg} = 11.2 \times 10^{3} N

Therefore, the  the average magnitude of the force exerted on the ball by the floor 11.2 \times 10^{3} N

Sholpan [36]

Answer:

(d) 22.22 °C

Explanation:

Because in 1 Celcius is 1.8 fahrenheit apart from 2 celcius, so

when °C is 0 f is 32, when °C is 1 = 33.8 , so it rises with quantities of 1.8 fahrenheit
