A ball of mass 0.2kg with velocity 10m/s strikes a bat and return with the same velocity in 0.01 sec. Find F ( force ) on the bat :

A. 200N
B. 250N
C. 20N
D. 205N

billu004: ur option r wrong answer should be 400N or u had made a mistake somewhere in question

billu004: r the options right

m=0.2kg, v=10m/s , t=0.01sec F=ma
F=mv÷t
F=0.2×10÷0.01
F=200N

adinazahid2: No problem dear, thankyou

Answered by kspaneserpcd1d9

looks 200 N from. 0.2*10÷0.01

adinazahid2: Dear the velocity of both cases is same . Here is a relationship of force with mass and time.

adinazahid2: We know that F=ma

adinazahid2: M iws mass andd a is acceleration means v/t

billu004: u r not getting me but I am 100% sure that there is some mistake in ur question

billu004: the answer will be 400N and I am sure

billu004: I have no doubt about it

adinazahid2: Okay let me check the question again. May be I am wrong . Lets take it easy

billu004: and post the original question

billu004: is the question correct
