Because gravity is constant
<span>the only force acting in free-fall is gravity which points downward at 9.8 m/s</span>
Answer:
1700 Joules
Explanation:
Work=force x distance
Force = 170 kg
Distance= 10 Meters
170 x 10 = 1700 Joules of work
write out what you have on both sides, then just use basic multiplication to try and even out both sides. I can help if you need me to balance some for you!!
Answer:
D.
Explanation:
acceleration in the z component = velocity in z component / time. The question states velocity in z component is zero. Therefore, acceleration in z component = 0/time = 0.
Now the question does not specify whether the other velocity vectors (x or y) is zero or not. So its D.
