Question

in a football match a ball is kicked by a player with a force of 25N for 0.2secs and then by another player with a force of 70 N for 0.1sec in the same direction.if the football gains a velocity of 24 m/s after the two kicks,the mass of the football is nearly? plz answer I will mark as the Brainliest​

Answer 2

Answer:

Explanation:

The total time taken is 0.3 seconds, the velocity of the ball is 24 m/s and the total force generated by both player is 70+25= 95 N.

Applying Newtons first law of motion we have v=u+at which on solving we have 24=a*0.3 or acceleration a will be 80m/s^2. Hence, after the two kicks the mass of the football is force F=mass(M)*acceleration which on solving we have M=F/a or M=95/80 = 1.055 kg will be the mass of the football.
