A motorbike accellerates from 15m/s to 25m/s in 15 seconds. How far does thew motrobike trsavel in this time?

300 m.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 15 m/s

Final velocity (v) = 25 m/s

Time (t) = 15 secs

Distance (s) =?

The distance travelled by the motorbike can be obtained as follow:

s = (u + v)t / 2

s = (15 + 25) × 15 / 2

s = 40 × 15 / 2

s = 600 / 2

s = 300 m

Thus, the distance travelled by the motorbike is 300 m.

i. like it i'm gonna edit it tomorrow

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
