Answer:
0.25683
Explanation:
t = Time taken by the truck to stop = 11 seconds
u = Initial velocity of the truck = 62 mi/h
v = Final velocity of the truck = 0
a = Acceleration of the truck
g = Acceleration due to gravity = 9.81 m/s²
Equation of motion


The minimum coefficient of static friction between the turtle and the truck bed surface needed to prevent the turtle from sliding is 0.25683
Answer:
I think the answer is 18 km/h
Explanation:
Answer:
Explanation:
This problem is related to vertical motion, and the equation that models it is:
(1)
Where:
is the rock's final height
is the rock's initial height
is the rock's initial velocity
is the angle at which the rock was thrown (directly upwards)
is the time
is the acceleration due gravity in Planet X
Isolating
and taking into account
:
(2)
(3)
(4) This is the acceleration due gravity in Planet X
