Man, Money and Machine
Use Pythagoras' Theorem to find its value. For example, if it was moving at 3ms-1 in the x direction and 4ms-1 in the y direction, its absolute velocity would be the square root of (9+16), 5ms-1.
F=ma: m = 650kg a = 3ms-2 ( m/s2 ) 650 x 3 = 1950N (1.95kN)
And what is the question? If you want the average acceleration for that time, divide the change in velocity, by the time elapsed.
The maximum height of the lollipops can be calculated using the kinematic equation ( \text{max height} = \frac{v^2}{2g} ), where ( v = 3ms ) and ( g = 9.81ms^2 ) (acceleration due to gravity). Plugging in the values, we get ( \text{max height} = \frac{3^2}{2 \times 9.81} \approx 0.46m ).
It is 40500J.
3M Company (NYSE: MMM), formerly Minnesota Mining and Manufacturing Company until 2002, is an American multinational conglomerate corporation.
If your printer is on your network and is set to get its ip by DHCP, your router's utility program ought to display the address. For instance, you would go to your router's ip (usually something like 192.168.0.1) and log into the router with the admin password and dig around for the list of devices that are connected. In Windows you could also open the printer's control panel and find its network name. If you know its network name you open a command prompt and ping the name. In this example, you can see that the printer's name is "kodakaio": C:\Users\JSB>ping kodakaio Pinging kodakaio [192.168.0.103] with 32 bytes of data: Reply from 192.168.0.103: bytes=32 time=3ms TTL=60 Reply from 192.168.0.103: bytes=32 time=2ms TTL=60 Reply from 192.168.0.103: bytes=32 time=3ms TTL=60 Reply from 192.168.0.103: bytes=32 time=2ms TTL=60 Ping statistics for 192.168.0.103: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 2ms, Maximum = 3ms, Average = 2ms
1.93 m/s
Calculate the difference in velocity, Then divide that by the time. The result will be the acceleration, in this case, in meters per second squared.
Q1 = ( V1 ) ( A1 ) = ( 3 m/s ) ( A1 )Q2 = ( V2 ) ( A2 ) + ( 3 m/s ) ( A2 )A3 = A2 = A1Q3 = Q1 + Q2V3 = ( Q1 + Q2 ) / ( A1 )V3 = ( A1 ) ( 3 m/s + 3 m/s ) / ( A1 ) = 6 m/s
The momentum of the ball can be calculated using the formula: momentum = mass x velocity. Substituting the values: momentum = 2 kg x 3 m/s = 6 kg m/s.
