A flashlight has a flow of a direct current.
answer:
2.5 m/s²
Explanation:
120 km/h = 120 ÷ 3.6 = 100/3 ≈ 33 m/s
a = (v2 - v1)/∆t = (33m/s - 0)/ 13s = 33/13 m/s²≈ 2.5 m/s²
None of the above
mass is measurement of how much stuff in inside something.
if you freeze or heat an object, you merely change the state of the object. the mass is conserved.
if you change the elevation, nothing happens to the mass. the stuff will not leave the object.
so it is None of the above
Answer:
v'=0.83m/a and v=10.2m/s
Explanation:
The information that we have is:
The maximum height of the projectile is given by the equation
So, rearrange for the velocity,
Apply the conservation of momentum,
Then rearrange the recoil speed,
-- When the man at the North end throws the ball, the canoe
accelerates to the North.
-- While the ball is in flight, traveling south by the length of the
canoe, the canoe moves northward at a constant speed.
-- If the man at the south end misses the ball and fails to catch it,
then the canoe continues moving south at a constant speed, even
after the ball has passed him.
-- If the man at the south end successfully catches the ball, then the
canoe accelerates south at that moment, and comes to rest in the water.
