The correct answer is violet and red.
Answer:
2.846m
Explanation:
The diver is performing projectile motion.
To find x(final), we are going to use the equation x(final) = v(initial)*t + x(initial)
x(initial) = 0
x(final) = ?
v(initial) = 2.3 m/s
we don't know t
To find t we will use y(final) = 1/2*(-9.8)*t^2 + v(initial in the y dir.)*t + y(initial)
- 9.8 in the acceleration in the y dir.
y(final) = 0
y(initial) = 7.5
v(initial in the y dir.) = 0
If we solve for t we get: t = 1.237s
Now we have all the components to solve for x(final) in x(final) = v(initial)*t + x(initial)
x(final) = 2.3*1.237 + 0
x(final) = 2.846m
E=mgh. 196=5kg*9.81m/s^2*h. So h=196/(5*9.81)=4m
The answer is insulator like rubber, wood stuff like that ^-^
Newton's second law of motion says:
Force = (mass) x (acceleration)
88 = (mass) x (4)
Divide each side by 4 :
Mass = 22 kg.
