Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.
For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.
Answer:
the rate of turn at any airspeed is dependent upon the horizontal lift component
Impulse = Change in momentum.
The ball was moving with a momentum of 0.45 * 22 = 9.9
The ball comes to rest in the receivers arm; this means the ball's final velocity = 0. So mv2 = 0.45 * 0
The magnitude of the impact is just the change in momentum. 9.9 - (0.45 * 0) = 9.9
Answer:
Explanation:
Given that,
Mass of the clock, m = 108 kg
When the clock is not moving, force acting on it, 
For the clock in motion, force acting on it, 
To find,
Solution,
When an object is at rest, the force acting on it is called force due to static friction and if the object is in motion, the force acting on its called force due to kinetic friction.
Let 
is the coefficient of static friction. Force is given by :
Let 
is the coefficient of kinetic friction. Force is given by :
Or get Chegg, it’ll work!!!
