On the moon, the gravitational acceleration is 1/6 of 9.8 m/s², so
g = 9.8/6 = 1.633 m/s²
Launch speed = 35 m/s
Launch angle = 27° above the horizontal.
Therefore,
The horizontal velocity is
u = 35*cos(27) = 31.1852 m/s
The vertical launch velocity is
v = 35*sin(27) = 15.8897 m/s
Part A
When the ball reaches maximum height, the time requires is given by
0 = v - gt
t = v/g = 15.8897/1.6333 = 9.7286 s
This is one half of the time of flight, which is
2*9.7286 = 19.457 s
Answer: 19.46 s (2 sig. figs)
Answer:
A
Explanation:
You are given Vi, Vf and t. The only thing left is a.
Answer:
The wavelength decreases as the electron speeds up. The wavelength increases as the electron slows down.
Explanation:
Answer:
Yes, because the wrench is moving at the same speed as the sailboat.
The main difference is that a person on the ground would see the wrench moving diagonally, while a person on the boat would see the wrench falling straight down,
This difference in paths lead to the relativistic change in lengths.
