In the game of curling a large stone is sliding along the ice (zero friction) toward a target (somewhat like bowling). If a 20 kg curling stone sliding at 3.5 m/s strikes another identical stone at rest and causes it to move off along the original stone's path. A). Calculate the resultant speed of the first stone if a force of 1000 N acts for a time of 50 ms.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
