Answer:
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.
