A. Two objects coming in contact with each other
Answer:
Distance covered is: 45 meters
Displacement is 15 meters to the right of where he started
Explanation:
Notice that Brady has walk a path that looks like an incomplete rectangle of height 5 meters and length 25meters, although he actually didn't cover the full length (25 meters) when getting back to the point where he started (he made just 10 meters instead of 25 after the third turn right) See attached image.
Therefore, Brady's displacement is 15 meters to the right of where he started, and the total distance he covered is :
Distance = 5m + 25m + 5m + 10m = 45m
Answer:
thickness of ice melted = 1.242*10^{-3} m
Explanation:
power delivered = V*I = 12 * 28 = 336 Watts
.
heat delivered = power * time = 336 W * 300 seconds = 168000 Joules
.
mass of ice melted
mass of ice melted = 97200 J / 335000 J/kg = 0.5014 kg
.
volume of ice melted = mass / density = 0.5014 / 917 = 5.46*10{-4} m3
.
thickness of ice melted = volume / area = 5.46*10{-4} / 0.44 = 1.242*10^{-3} m

Answer:
6.1 m^2
Explanation:
first subtract 10(the friction force) from 27.
acceleration=force/mass
