Question

hello I have task were a ball is thrown in a horizontal projectile motion and we are am given the Range of Flight= 1.02 m Time of flight= 1.20 sec and Height of launch= 1 meterI need to help finding- the initial velocity -time of the highest point - and the velocity of ball after impact

Answer 1

Given data:

* Range of the flight given is,

`R=1.02\text{ m}`

* The time of the flight is,

`T=1.2\text{ s}`

* The height of the launch is,

`H=1\text{ m}`

Solution:

(a). The initial velocity of the horizontal projectile is,

`\begin{gathered} R=uT \\ u=(R)/(T) \end{gathered}`

Substituting the known values,

`\begin{gathered} u=(1.02)/(1.2) \\ u=0.85ms^(-1) \end{gathered}`

Thus, the initial velocity of the projectile is 0.85 meter per second.
