Question

A body projected upward with the velocity of 30m/s.how height would it raise

Answer 1

Answer -

Given -

• Initial velocity = 30 m/s

• Acceleration due to gravity = -9.8 m/s² ( because it is thrown upward )

• Final velocity = 0 ( due to maximum height )

To Find -

• Maximum height

Solution :-

Substituting these values is 3rd equation of motion -

➩ $\sf v^2 = u^2 + 2as$

➩ $\sf 0 = 30^2 - 2 \times 9.8 s$

➩ $\sf 30^2 = 19.6 s$

➩ $\sf s = \frac{900}{19.6}$

➩ $\sf s = 46 \:( approx )$

Maximum height = 46 m
