Explanation:
Given that,
Mass of a skier, m = 55 kg
The vertical distance between start and finish is 10 m.
(a) The potential energy of a skier is given by :
(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,
Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.

Incandescence is light at high temp
Answer:
The answer to your question is: F = 924 N
Explanation:
Data
v = 28 m/s
m = 66 kg
d = 56 cm
F = ?
Formula
v = d/t
a = v/t
F = ma
Process
t = d/v = 56 / 28 = 2 s
a = v/t = 28 / 2 = 14 m/s²
F = 66 (14) = 924 N
