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
=>
initial speed of the racer is given as
after applied force the final speed is given as
now during this speed change the racer will cover total distance 185 m
so here we will use kinematics
now the force that chute will exert on the racer will be given as
B) here following is the strategy for solving it
1. first we used kinematics to find the acceleration of the car
2. then we used Newton's II law (F = ma) to find the force
Answer "d' no charge
Explanation:
They are as the name says neutral. They have no charge they are electrically neutral. Just as a proton is a positively charged particle and an electron carries a negative charge.
Answer:
any planet orbiting the Sun does so at constant
