The answer is high temperatures
The acceleration due to gravity at the Earth's surface is 9.8 m/s/s
<span>So a 2 kg object will accelerate at 9.8 m/s/s if it is dropped..... actually all dropped objects will accelerate at the same rate. </span>
<span>The force of gravity on the object is given by Newton's 2nd Law </span>
<span>F = m . a </span>
<span>F = 2 . 9.8 = 19.6 N </span>
<span>Now go to Mars , with a lower gravitational field strength. It only accelerates falling objects at 3.71 m/s/s </span>
<span>So the force of gravity on the object is F = 2 . 3.71 = 7.42 N </span>
<span>But the answer is (2) 2 kg, because the mass of the object stays the same and that is what you are asked for. </span>
<span>Someone was trying to be tricky.</span>
Answer:
It will take. the same distance up as before, but take a longer time
Vf=√30²+100²
Vf=104 m/s
|Ф|=tan inverse of |100÷30|
Ф= 73 degrees
Therefore the resulting velocity of the airplaine is 104 m/s [ 73 degrees N of W]
Answer: 2.67
Explanation: it said he went from 0 to 8 in 3 seconds so if we divide eight By three we get 2.67 rounded to the nearest hundredth so you accelerated that 2.67 m/s
