Acceleration = change of velocity / time taken = 25/5 = 5 m/s/s
Answer:
Time period is directly proportional to the length so if the length is doubled the time period is doubled
hope it is helpful....
Answer:
Explanation:
given that
Distance above the ground, s = 1.2 m
Time taken by the ball, t = 3 s
Velocity of the ball, v = 1.2/3 = 0.4 m/s
Maximum height reached by the ball is then given by the formula
H = v² / 2g
H = 0.4² / 2 * 9.8
H = 0.16 / 19.6
H = 0.0082 m or rather, 0.82 cm
