Answer:
the mass of the raft is 68.4 kg
Explanation:
Since Mass is defined as Volume times Density, start by calculating the volume of the raft:
Volume = length x width x high = 1.5 m x 1.0 m x 0.12 m = 0.18 m^3
and now multiply it times the given density in order to find its mass:
Mass = Volume x Density = 0.18 m^3 x 380 kg/m^3 = 68.4 kg.
Notice that the m^3 units cancel out (they are in numerator and in denominator) leaving just the kg (a unit of mass) in the answer.
Therefore, the mass of the raft is 68.4 kg
Answer:
The minimum possible coefficient of static friction between the tires and the ground is 0.64.
Explanation:
if the μ is the coefficient of static friction and R is radius of the curve and v is the speed of the car then, one thing we know is that along the curve, the frictional force, f will be equal to the centripedal force, Fc and this relation is :
Fc = f
m×(v^2)/(R) = μ×m×g
(v^2)/(R) = g×μ
μ = (v^2)/(R×g)
= ((25)^2)/((100)×(9.8))
= 0.64
Therefore, the minimum possible coefficient of static friction between the tires and the ground is 0.64.
F=m•a(squared)
F=8,000•4(squared)
F=8,000•16
F=128,000
then divide by 2 which is
64,000 Joules
