The car's average speed during that time is (23.7/2) = 11.85 m/s .
Distance = (11.85 m/s) x (6.5 sec) = 77.025 meters .
Well a simple answer would be it would start to melt because icecream is a liquid unless its frozen,just like ice.
Answer:
400 N
Explanation:
Change of Kinetic Energy to Friction Wok
∆KE = W
½ x m x (v(5)² - v(3)²) = f x d
½ x 500 x (5² - 3²) = f x 10
250 x (25 - 9) = f x 10
25 x 16 = f
f = 400 N
