The maximum height attained by the ball is 60 m.
<h3>What is the maximum height?</h3>
We know that the maximum height can be obtained from the equation;
v^2 = u^2 - 2gh
v = final velocity
u = initial velocity
g = acceleration due to gravity
h = maximum height
Since the final velocity is 0 m/s at maximum height then;
u^2 = 2gh
h = u^2/2g
h = (34.3)^2/2 * 9.8
h = 60 m

Answer:
The weight lifter would not get past this sticking point.
Explanation:
Generally torque applied on the weight is mathematically represented as
T = F z
To obtain Elbow torque we substitute 4000 N for F (the force ) and 2cm for z the perpendicular distance
So Elbow Torque is
To obtain the torque required we substitute 300 N for F and 30cm
So the Required Torque is
Now since it mean that the weight lifter would not get past this sticking point
Answer: D
Explanation: Potential stores Kinetic Energy so, Point C will have Kinetic turned into Potential.
I think it’s A because ascending means going up 10,000 then descending is going down 2,000 so in all they are 8,000 feet above the ground
