Question

find out the time of ascending for an object thrown up with 70 m/s velocity​

Answer 1

Answer:

The ball is thrown upwards.

∴ Acceleration due to gravity =−9.8m/s

2

Final velocity = 0m/s

Initial velocity =25 m/s

Distance =35 m

Time =1.5 sec

To find total distance traveled: the distance traveled by the ball in upward and downward motion will be the same.

Hence, the total distance will be 35 m+35 m=70 m

To find position after 2 sec

Using the formula:

s=ut+
