Answer:
8.61 min
Explanation:
original mass= 12.65
first half life = 12.65/2 = 6.325
second half life = 6.325/2 = 3.1625
Note : 3.1625 is the closest to the value (3.115) given so we work with it
total time for decay =17.22
therefore two decays = 17.22/2= 8.61
Answer:
33.65°
Explanation:
radius, r = 53.1 m
m = 2.9 Mg = 2.9 x 10^6 g = 2900 kg
v = 67 km/h
convert km/h into m/s
v = 18.61 m/s
Let the angle of banking of road is θ, without friction
tan θ = 0.6655
θ = 33.65°
Thus, the angle of banking of road is 33.65°.

Momentum helps us quantify how much movement an object has. For example, if we want to know how much movement an object of 2 kg moving at 4 m/s has, we take their product.
