a1. A bus starting from rest has an acceleration of 0.1 m/s2. What will be the velocit of the bus after 20 seconds? [Ans: 2 m Two vehicles are moving in the same direction. The velocity of the first vehicle i 8 m/s and the velocity of the second vehicle is 5 m/s. Find their relative velocit What will be the relative velocity if they move in the opposite directions? [Ans: 3 m/s, 13 m g. A car is travelling in the velocity of 20 m/s. After 30 sec it covers a distance o 1200 m. Calculate the acceleration of the car and the final velocity of the car. [Ans: 1.14 m/s2, 54.2 A truck starts to move from rest. If it gains the acceleration of 3 m/s2 in 5 sec, calculate the final velocity and distance covered by the truck. [Ans: 15 m/s, 37.5 iple Choice Questions​

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
