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,

$\begin{gathered} R=uT \\ u=\frac{R}{T} \end{gathered}$

Substituting the known values,

$\begin{gathered} u=\frac{1.02}{1.2} \\ u=0.85ms^{-1} \end{gathered}$

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