Given:
Acceleration,a = 1 m/s²
Time taken,t = 10 sec
initial velocity, u = 0
To be calculated:
Calculate the maximum height reached by ball ?
Formula used:
- v = u + at
- h = v² / 2g
Solution:
According to the first equation of motion,
v = u + at
= 0 + 1 × 10
= 0 + 10
= 10 m/s
Now,
Height, h = v² / 2g
= ( 10 )² / 2 × 9.8
= 100 / 2 × 9.8
= 100 × 10 / 2 × 98
= 1000 / 196
= 5.10 m ( approx)
Thus, the maximum height is 5.10 m .
