Answer» mate ⭐⭐here is ur answer ➖➖➖➖➖➖➖⬇Given .. (1) time taken to take 10 shots=1 SEC ==> time taken to take one shot= 1/10 sec (2) Distance travelled by BALL while camera took 6 shots =15 METER We know , speed= distance/time Distance=15m Time= Not known... LETS find out the time to take six shots FIST shot was taken after = 0sec (as first short was taken at beginning) Second shot taken after = 1*(1/10) = 1/10 seconds Third short taken after = 2*(1/10) =2/10 seconds Similarly .. sixth shot taken after = 5*(1/10) =5/10 Now.. speed = distance/time = 15 / (5/10) = 30 m/second Hope, it helps.please mark as a brainliest ✌☺❤✍ |
