Her magnitude of deceleration on the ice would be 15.126m/s
Answer:
95 calories
Explanation:
A medium-sized apple has only 95 calories but plenty of water and fiber.
The formula for a kinetic energy KE of a falling body is
KE = mgh
where m = mass, g = acceleration due to gravity (9.8 m/s^2, constant), h = height.
The total mass of a skateboader and a skateboard is 64 + 2.0 = 66 kg.
Finally,
KE = 66*9.8*5.0 = 32340 J
According to e2020, the answer is reduced performance due to stereotype threat.
