Answer: 45kg
Explanation:
Since 25% of the ingot consists of zinc, it implies that (100 - 25) = 75% of copper is contained in the ingot.
We then calculate 75% of 60kg to get the amount of kilograms of copper that the ingot of brass contain. This will be:
= 75% × 60
= 75/100 × 60
= 0.75 × 60
= 45kg

Answer: 8 m/s²
Explanation:
v₀ = initial velocity of the roller coaster at the top of hill = 10 m/s
v = final velocity of the roller coaster at the bottom of hill = 26 m/s
a = acceleration of the coaster = ?
t = time of travel = 2 sec
using the kinematics equation
v = v₀ + a t
inserting the values
26 = 10 + a (2)
subtracting 10 both side
26 - 10 = 10 - 10 + 2 a
16 = 2 a
dividing both side by "2"
16/2 = 2a/2
ans: 8 m/s²
