Answer:
D_momentum = 3.23[kg*m/s]
Explanation:
The change of moment can be easily determined by applying the principle of momentum and amount of movement
initial data are:
Whenever a vehicle is in motion, it has got kinetic energy. Kinetic energy has a direct relationship with the stopping distance. Kinetic energy is dependent on the mass of the vehicle and also the velocity at which it is traveling. In case of a small vehicle, the mass of the vehicle will be small and so the stopping distance will also be less compared to a large vehicle. In the case of the large vehicle traveling at the same velocity as the small vehicle, the stopping distance will be greater because the large vehicle has a larger mass. So in case of a small vehicle the kinetic energy will be less and so the distance for stopping will be less than that of the large vehicle.
Object's centripetal acceleration is 20 m/s^2
An object moving in a circular path with a constant speed, does have an acceleration, as it changes its direction as the object rotates. This centripetal acceleration can be found using below mentioned relation:
Ac(centripetal acceleration) = (v^2)/r; where, v is the constant speed of object and r is the radius of circular motion
Therefore, Ac = 10*10/5 = 20 m/s2
Rise over run at 1 second
It’s the same slope from 0 to 2 seconds
10/2=5mps
As a note all time points between 0and 2 will have this instantaneous velocity
Instantaneous velocity at time 2 is 0
Answer:
When you release the opening of the balloon, gas quickly escapes to equalize the pressure inside with the air pressure outside of the balloon. The escaping air exerts a force on the balloon itself. ... That opposing force—called thrust, in this case—propels the rocket forward.
