What is the unit of acceleration due to gravity ?
m/s
m/s2
m2/s
none of these
Unit of acceleration due to gravity is msec2
What is meant by the statement that acceleration due to gravity is 9.8m/s2?
A ball is thrown vertically upwards with a speed of 19.6 m/s from the top of a tower, and it returns to the base of the tower in 6s. Find the height of the tower. [Acceleration due to gravity g=9.8 m/s2]
A ball thrown vertically upwards with a speed of 20m/s from the top of a tower reaches a certain height and then falls back to the earth in 6 s. Find the height of the tower. [Take acceleration due to gravity, g=10 m/s2]
Which of these can be the units of 'g' (acceleration due to gravity) ?
