Answer:
The velocity is
Explanation:
From the question we are told that
The mass of the bullet is
The initial speed of the bullet is
The mass of the target is
The initial velocity of target is
The final velocity of the bullet is is
Generally according to the law of momentum conservation we have that
=>
=>
Answer:
B. 0.16 m
Explanation:
The vertical distance by which the player will miss the target is equal to the vertical distance covered by the dart during its motion.
Since the dart is thrown horizontally, the initial vertical velocity is zero:
While the horizontal velocity is
The horizontal distance covered is
Since the dart moves by uniform motion along the horizontal direction, the time it takes for covering this distance is
along the vertical direction, the motion is a uniformly accelerated motion with constant downward acceleration g=9.8 m/s^2, so the vertical distance covered is given by
Answer:
Explanation:
Suppose when bucket is half full it has a mass of 2 m rotating in a circle of radius r
When Bucket is quarter full then it has a mass of m rotating in a circle of radius r.
When an object moves in a circular path then it experiences an inward force which is given by
where v=velocity of bucket
Force in case 2 is given by
Thus
therefore force required in half bucket is more than force required in quarter bucket full.
