The range of a projectile is the maximum horizontal distance between the point of origin to the end point. It can be calculated through the equation,
range = v²sin2θ/g
where v is the initial velocity, θ is the angle, and g is the gravitational constant.
Substituting the known values,
range = (36 m/s)² x (sin2(28°)) / 9.8 m/s²
range = 109.64 m
Thus, the range of the golf ball is approximately 109.64 m.
Let's cut through the weeds and the trash
and get down to the real situation:
A stone is tossed straight up at 5.89 m/s .
Ignore air resistance.
Gravity slows down the speed of any rising object by 9.8 m/s every second.
So the stone (aka Billy-Bob-Joe) continues to rise for
(5.89 m/s / 9.8 m/s²) = 0.6 seconds.
At that timer, he has run out of upward gas. He is at the top
of his rise, he stops rising, and begins to fall.
His average speed on the way up is (1/2) (5.89 + 0) = 2.945 m/s .
Moving for 0.6 seconds at an average speed of 2.945 m/s,
he topped out at
(2.945 m/s) (0.6 s) = 1.767 meters above the trampoline.
With no other forces other than gravity acting on him, it takes him
the same time to come down from the peak as it took to rise to it.
(0.6 sec up) + (0.6 sec down) = 1.2 seconds until he hits rubber again.
Answer:
Explanation:
A )
As the two bicycles come closer , the time period of oscillation of bee to oscillate between the two is gradually reduced . It is akin to a pendulum with gradually decreasing amplitude . It will be infinite number of trips the bee will travel before it gets squished .
B )
The bee will survive until the two bicyclists meet each other .
time of their meeting = distance between them / their relative velocity
= 20 / ( 10 + 10 )
= 1 hour .
C )
Total distance travelled by bee during 1 hour
= time x speed of bee
= 1 x 30 km/h
= 30 km .
The world’s supply of fossil fuels will dwindle slowly until a replacement source is found that provides the same power.
bc some day we will actually run out of it and find sth that gives power
This is called super-saturation
hope this helps :)))))))
