Answer:
f. Force acting down and constant
Explanation:
At the highest point, the coin will start to free fall and in free fall only force of gravity act, which is always acted downward and its magnitude is mass times g. g=9.81 m/s^2. which makes the force constant.
therefore, the correct answer will be f. Force acting down and constant
Answer:
a) Her feet are in the air for 0.73+0.41 = 1.14 seconds
b) Her highest height above the board is 0.82 m
c) Her velocity when her feet hit the water is 7.16 m/s
Explanation:
t = Time taken
u = Initial velocity = 4 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
b) Her highest height above the board is 0.82 m
Total height she would fall is 0.82+1.8 = 2.62 m
a) Her feet are in the air for 0.73+0.41 = 1.14 seconds
c) Her velocity when her feet hit the water is 7.16 m/s
