1) v=u+gt = -5 +10*2=15 m/s
2) r=ut+gt^2/2=-5*2+10*2^2/2=-10+20=10m
3) r of heli= vt =5*2=10m
So 10m by bag from answer number 2 plus additional 10m by helicopter equals 20m
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

<span>According to Newton’s law of universal gravitation, the sun would have more gravity than earth because it is more massive (has more mass).

A thermal conductor is an item that can conduct thermal energy or temperature, much like a knife.
Metals often feel cool to the touch because the are thermal conductors, storing cool energy making them feel cooler.
Using thermal energy is like taking a knife and warming it up so it can better cut through objects.
