Answer: law of conservation of matter states that mass in an isolated system can neither be created nor destroyed by chemical reactions or physical transformation.
thus, the mass of the reactants in a reaction must be equal to the mass of the products
Answer:
10.1 ms^-2
Explanation:
From;
v = u + at
v = final velocity
u = initial velocity
a= acceleration
t = time taken
To convert the velocity from Km/hr to m/s we us;
x * 1000/3600
Where x is the velocity in Km/hr
So;
799 * 1000/3600 = 221.9 m/s
11325 * 1000/3600 = 3145.8 m/s
4.8 minutes = 4.8 * 60 = 288 s
Applying the formula;
a= v - u/t
a = 3145.8 - 221.9/288
a = 10.1 ms^-2
