A 0.45 kg soccer ball changes its velocity by 20.0 m/s due to a force applied to it in 0.10 seconds. What force was necessary fo
frutty [35]

Answer:

90 N

Explanation:

The force applied to the ball is given by:

F=\frac{\Delta p}{\Delta t}

where

\Delta p is the change in momentum of the ball

\Delta t is the time taken

The change on momentum of the ball is:

\Delta p=m\Delta v=(0.45 kg)(20 m/s)=9 kg m/s

So, the force applied is

F=\frac{9 kg m/s}{0.10 s}=90 N

(I) A novice skier, starting from rest, slides down an icy frictionless 8.0° incline whose vertical height is 105 m. How fast is
Vlad1618 [11]

Answer:

v = 45.37 m/s

Explanation:

Given,

angle of inclination = 8.0°

Vertical height, H  = 105 m

Initial K.E. = 0 J

Initial P.E. = m g H

Final PE = 0 J

Final KE = \dfrac{1}{2}mv^2

Using Conservation of energy

KE_i + PE_i + KE_f + PE_f

0 + m g H = \dfrac{1}{2}mv^2 + 0

v = \sqrt{2gH}

v = \sqrt{2\times 9.8 \times 105}

v = 45.37 m/s

Hence, speed of the skier at the bottom is equal to v = 45.37 m/s
