A projectile fired from a gun has initial horizontal and vertical components of velocity equal to 30 m/s and 40 m/s, respectively. 3. Approximately how long does it take the projectile to reach the highest point in its trajectory

The time is 5.10 sec.

Explanation:

Given that,

Component of velocity are 30 m/s and 40 m/s.

We need to calculate the resultant velocity

Using formula of resultant velocity

Put the value into the formula

[

We need to calculate the time

Using equation of motion

Put the value into the formula

Hence, The time is 5.10 sec.
