Answer:
Forces, Gravity, Friction, Direction, Acceleration.
Answer:
Explanation:
In this case we have to use the Principle of conservation of Momentum:
<em>This principle says that in a system the total momentum is constant if no external forces act in the system. The formula is:</em>
<em>Where:</em>
Mass of the first object.
Mass of the second object.
Initial velocity of the first object.
Initial velocity of the second object.
Final velocity of the first object.
Final velocity of the second object.
In <u>this problem</u> we have:
Observation: 
Is because the system has the same initial velocity.
First we have to find 
,
We can rewrite it as:
Replacing with the data:
We found the final velocity of the cart, but the problem asks for the resulting change in the cart speed, this means:
Then, the resulting change in the cart speed is:
If the ground is level, then the snowball can never have
any more kinetic energy than it hand when it left your hand.
If more mass sticks to it as it makes its way across the lawn,
then it must slow down, so that its
KE = (1/2) (present mass) (present speed)²
never exceeds the KE you gave it when you tossed it.
And we're not even talking yet about all the energy it loses
by scraping through the snow and mashing down the blades
of grass in its path.
Answer:
B. Technician B
Explanation:
The statement made by Technician A is not right because for an RWD vehicles, its front bearing assembly is not used for sustaining the bearing adjustment. The statement made by the Technician B is right because the main reason for staking the bearing assembly of the wheel of a FWD vehicle is to ensure that the torque is at a specific value. Thus, only Technician B is correct.
