Question

A ball is thrown vertically upwards with a velocity of 49 metre per second and acceleration is 4.8 metre per second square calculate the maximum height to which Rises and the total time taken to return to the surface of Earth ​

Answer 1

Answer:HIII

Explanation: WHAT<<<<<>>>>>??????

Answer 2

Answer:ti me taken to freach the ground is 10 sec

and maxm height reached will be approax 125 m

Explanation:

v=u-at from here will get v=0 at 5 sec

and we know time of ascend is equal to time of descent so 5+5 =10

now by using

v2-u2=2as

v2 =0 and u2=49*49 and 2a=9.8*2

so from here we can calculate s= v2-u2/2a after putting all the values ans will be approax to 125
