a tennis ball is firstly applied with force F1 to produce an acceleration of 5m/S2. then it is applied force F2 to produce an acceleration of 10m/S2 find the ratio of F1 and F2​

Answer»

ong>Answer:

F1/F2=1/2

Explanation:

HERE MASS OF THE BALL IS CONSTANT(SAME) IN BOTH CASES

F1=MA

F2=MA

NOW SUBSTITUTING VALUES

F1=M5

F2=M10

NOW TO FIND THE RATION WE NEED TO DIVIDE F1/F2

WE CAN ALSO DIVIDE M5/M10 AS F1 AND F2 ARE EQUAL TO M5 AND M10 RESPECTIVELY

NOW

M5/M10

AS MASS IS CONSTANT WE CAN CANCEL

5/10= 1/2

HENCE

F1/F2=1/2
