Question

A skier is traveling fast down a mountain slope. The table shows data
collected on the skier at a particular instant.
Mass
64 kg
Weight
608 N
Velocity
21 m/s, forward
Force of skier pushing forward
45 N, forward
Which data are needed to determine the reaction force of the snow pushing
on the skier?
O A. The pushing force and the skier's mass
B. The skier's mass and velocity
C. The skier's weight and acceleration
D. The force of the skier pushing forward

Answer 1

Answer:

The pushing force and the skier's mass

(A) is correct option.

Explanation:

Given that,

Mass = 64 kg

Weight = 608 N

Velocity = 21 m/s

Forward force = 45 N

We need to calculate the reaction force of the snow pushing  on the skier

Using given data,

The reaction force of the snow pushing  on the skier is equal to the pushing force and the skier's mass.

Hence, The pushing force and the skier's mass

(A) is correct option.

Answer 2

Answer:

A. The pushing force and the skier's mass

Explanation:
