Answer:
Displacement of the ball in 5 sec when it is thrown from in upward direction with
speed 40 m/s is 75m.
Explanation:
Given:
Time, t = 5 sec
Speed, v = 40 m/s
Acceleration due to gravity, g = 10 m/s
To Find:
The displacement of ball in 5 sec, when it is thrown from in upward direction with speed 40 m/s.
Formula to be used:
Height, h = Vi × t + g/2 t²
Solution:
To find the displacement = ?
→ h = Vi × t + g/2 t²
→ h = 40 × 5 + (-10/2) × (5)²
→ h = 200 - 125
→ h = 75 m
∴ Displacement of the ball in 5 sec when it is thrown from in upward direction with speed 40 m/s is 75m.
