Answer:
The maximum height of the ball is 2 m.
Explanation:
Given that,
Mass of ball = 50 g
Height = 1.0 m
Angle = 30°
The equation is
We need to calculate the velocity
Using conservation of energy
Here, ball at rest so initial kinetic energy is zero and at the bottom the potential energy is zero
Put the value into the formula
Put the value into the formula
We need to calculate the maximum height of the ball
Using again conservation of energy
Here, h = y highest point
Put the value into the formula
Put the value of y in the given equation
Hence, The maximum height of the ball is 2 m.
