Explanation:
Exothermic reaction are those in which heat releases during a reaction
Answer:
When an object moves in a straight line with a constant acceleration, you can calculate its acceleration if you know how much its velocity changes and how long this takes.
The formula is,
Acceleration = change in velocity / time taken
The equation for acceleration can also be represented as:
a = (v-u) \ t
The change in velocity v – u = 5 – 0 = 5 m/s.
The acceleration = change in velocity ÷ time = 5 m/s ÷ 2 s = 2.5 m/s^2
The answer is that it is true
The Net force is 280 N (300-120). The acceleration = force / mass = 280 / 45 = 6.2 m/s^2
