Answer:
1. A burning streak of light, called a Meteor.
2.The rocky bodies that survives the fall to the planet’s surface are Meteorites.
Explanation:
Let us see the difference between them.
- Asteroids: They are the remnants of a broken planet orbiting the sun in between Mars and Saturn. They are small rocky bodies from a tennis ball size to larger ones weighing a few tones.
- Meteoroids: They are the small rocky objects of pebble size formed due to the collision of asteroids.
-
Meteors: These are pebble size objects that enter Earth's atmosphere and burns off by forming streaks of light.
- Meteorites: These are rocky objects bigger than meteors than don't burn out completely and fall on the earth's surface.
-
Comets: These are objects mainly made of dust and ice that orbit the sun in a highly elliptical orbit. This composition makes a long tail when approaching the sun.
The shot putter should get out of the way before the ball returns to the launch position.
Assume that the launch height is the reference height of zero.
u = 11.0 m/s, upward launch velocity.
g = 9.8 m/s², acceleration due to gravity.
The time when the ball is at the reference position (of zero) is given by
ut - (1/2)gt² = 0
11t - 0.5*9.8t² = 0
t(11 - 4.9t) = 0
t = 0 or t = 4.9/11 = 0.45 s
t = 0 corresponds to when the ball is launched.
t = 0.45 corresponds to when the ball returns to the launch position.
Answer: 0.45 s
Answer:
-14.67
Explanation:
this is the answer because Calculating acceleration involves dividing distance by time, so now you to the opposite and multiply the acceleration times 9.
