Answer:12.92 N, 17.98 N
Explanation:
Given
Speed of ball
mass of ball (m)=0.057 kg
time (t)=0.25 s
(a)Average Force(F)
=12.92 N
(b)Intial velocity(u)
Final velocity (v)
Average Force
F=17.984 N
Answer:
The skier will be moving at 13.31 m/s.
Explanation:
To calculate the velocity of the skier we need to find the acceleration, as follows:
Where:
: is the force due to the rope = 365 N
: is the combined average frictional force = 190 N
m: is the mass = 75.0 kg
Now, we can calculate the velocity of the skier by using the following kinematic equation:
Where:
: is the final velocity =?
: is the initial velocity = 0 (the skier is initially at rest)
d: is the distance = 38.0 m
Therefore, the skier will be moving at 13.31 m/s.

The three units used to express pressure are pascal (Pa), atmosphere (atm), and Hg (torr).
Answer:
Take up space
Explanation:
Actually we know this by the definition of matter which states that "matter is any substance that has mass and takes up space by having volume."
