30 km/h x 3 h = 90 km
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.

I assume you refer to the formula distance = velocity x time. If an object moves upward, the distance would become the height.
20 meters per second
I was not aware that they were similar except that they are both elements of dynamics.
1.5 km is a distance, not a speed.
Assuming that the car moves at a constant speed, you can use the standard formula for speed: distance = speed x time
I am going to assume you meant a constant speed of 1.5km/min. speed = distance/time distance = speed x time = 1.5km/min x 5.0min = 7.5km
Speed
Moves it out of area
Just divide the distance by the time. (In this case, the speed in the answer will be in meters per second.)
The definition of Work done is Force x distance moved. It does not matter how fast or slow it moves. Only how far it moves. Only distance traveled.
distance = rate x timedistance = (6.0m/sec)(8.0 sec)distance = 54 m
It is 1/2 times spring constant x distance squared. The spring constant k is force per inch and the distance is amount spring moves
Displacement is a value predicated on the shortest distance between an initial and final position. If a "body" moves a certain distance and returns to its original origin it has not technically traveled any distance based on this definition. The displacement will therefore be zero
Total distance travelled = 20m + 15m = 35m Total displacement travelled=20m - 15m =5m
v = H0D Where v is the velocity at which a galaxy moves away from us, and D is its distance. With H0 being the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v.
