One jet plane is flying east at 880km/h, and another plane is flying north at 880km/h. do they have the same velocities? the same speeds? explain.

The jet planes have different velocity but same speed.

Explanation:

Velocity is a vector quantity. It has both magnitude and direction. Speed has only magnitude. Both the jet planes have same speed that is 880 km/h but fly different directions. One plane flies towards East and another towards north. Thus, the planes have different velocities.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

where is the
