2. An aircraft was travelling at a speed of 80 ms when it landed on a runway. It took two minutes to stop. Calculate the acceleration of the aircraft while coming to a stop.
Ar.
ulate how for the car

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

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.

not too sure thinking all accelerations are pointed down
