Answer:
The speed is
Explanation:
From the question we are told that
The mass of the first skater is
The final speed of the first skater is
The mass of the second skater is
According to the principle of linear momentum conservation
Here
Since they they started from a stationary position
So
While
substituting values
So
=>
An Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
I hope this helped you with your problem.
Technically, displacement is the "shortest" distance between any two points. If you say displacement is greater than distance, you will contradict the above statement. Displacement is always less than or equal to distance. Note that distance is a scalar whereas displacement is a vector. :)
Answer:
the final velocity of the object is 53.04 m/s.
Explanation:
Given;
initial velocity of the projectile, u = 50 m/s
displacement of the object, d = 16 m
let the final velocity of the object = v
Apply the following kinematic equation to determine the final velocity of the projectile.
v² = u² + 2gd
v² = 50² + (2 x 9.8 x 16)
v² = 2813.6
v = √2813.6
v = 53.04 m/s
Therefore, the final velocity of the object is 53.04 m/s.
To change from mass to weight is Fw = 30 kg * 9.8 m/s^2 = 294 N. To change from weight to mass divide by gravity (9.8 m/s^2).
