Answer:
10 m/s
1.87914 s
18.7914 m
Explanation:
v = Initial velocity = 20 m/s
= Angle = 60°
Horizontal component is given by
The horizontal component is 10 m/s
y direction final displacement is zero
The time the ball is in the air is 1.87914 s
Range is given is by
The range is 18.7914 m
There isn't any relation between time and mass in speical relativity: mass is a Lorentz invariant, the same in all reference frames, time is the fourth component of the position 4-vector. Similarly, energy isn't a Lorentz invariant-it's the fourth component of the energy-momentum 4-vector.
Answer:
240 ft
Explanation:
t = Time taken
u = Initial velocity = 96 ft/s
v = Final velocity
s = Displacement
a = Acceleration = 12 m/s² on Mars 32 ft/s² on Earth negative due to upward direction
Mars
Earth
Differentiating the first equation with respect to time we get
Equating with zero
Differentiating the second equation with respect to time we get
Equating with zero
Applying the time taken to the above equations, we get
Difference in height = 384-144 = 240 ft
The stone will travel 240 ft higher on Mars
Those metals which conduct the electricity or heat partially, which may be good or bad conductors of heat and electricity is half -metals or semi metals.
