Answer: 2.63 m/s
Explanation:
The question in english is written below:
During an attemp of croquet game, a 0.52 kg ball at rest on the grass is hit by a mallet with an average force of 190 N, if the mallet is in contact with the ball for 
, Whay is the speed of the ball just after being hit?
According to Newton's second law of motion, the force 
exerted on an object is directly proportional to its mass 
and acceleration 
:
(1)
On the other hand, acceleration is defined as the variation of velocity 
in time 
:
(2)
Substituting (2) in (1):
(3)
Where:
Isolating the velocity from (3):
(4)
Finally:
Your weight will be less than on Earth because in space there is no or very less gravitational pull. There are no planets forming any magnetic fields for other objects to be attracted to.
Answer:
OD) 3.7 kg-m/s
Explanation:
given:
velocity of baseball, v = 25 m/s
angle below horizontal, Θ = 
mass of baseball, m = 0.15 kg
Generally, momentum (p) is given by equation:
p = mv
Horizontal component is given by
p = mv cosΘ
= 0.15 kg x 25 m/s x cos
= 3.71 kg- m/s
Hence horizontal component of momentum is OD) 3.7 kg-m/s
PART A)
horizontal distance that will be moved = 14 m
Height of the fence = 5.0 m
height from which it is thrown = 1.60 m
angle of projection = 54 degree
So here we can say that stone will travel vertically up by distance
now we will have displacement in horizontal direction
now we know that
now we will have
also for y direction
now from the two equations we will have
now from above equations
So the minimum speed will be 13.2 m/s
Part B)
Total time of the motion after which it will land on the ground will be "t"
so its vertical displacement will be
now we will have
Now the time after which it will reach the fence will be t1 = 1.8 s
so total time after which it will fall on other side of fence
now the displacement on the other side is given as
The answer to your question is A. At the same amplitude, the sound with the most cycles per sound will have the higher pitch.
