Acar of mass 960.0 kg accelerates away from an intersection on a horizontal road. when the car speed is 51.1 km/hr (14.2 m/s), the net power which the engine supplies is 3700.0 w (in addition to the extra power required to make up for air resistance and friction). calculate the acceleration of the car at that time.

Explanation:

The power supplied by the engine is given by

P = Fv

where

F is the force applied

v is the velocity of the car

Here we have

P = 3700 W

v = 14.2 m/s

So we can solve the equation to find the average force:

The net force applied on the car is also equal to

F = ma

where

m = 960.0 kg is the mass of the car

a is the acceleration

Re-arranging the equation, we find the acceleration:

multiply 2kg by latent heat of vap

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.
