A ferrari advertisement states that a certain car can accelerate from rest to 20 m/s in 7 seconds. Find the car’s average acceleration

2.9m/s^2

Explanation:

acceleration= final velocity-initial velocity / time

20m/s - 0m/s / 7 seconds

=2.9m/s^2

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

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.
