Express the following in S.I. units (a) 100 miles per hours, (b) 5 feet 2 inches

Text Solution

Verified by Experts

(a) 100 miles per hour
`=(100 xx 1.61 xx 10^(3))/(60 xx 60) = 1600/36 ms^(-1)`
`= 44.7 ms^(-1)`.
(b) 5 feet 2 inches.
`= 5 xx 12 +2 = 62` inches
`= 62 xx 2.54 xx 10^(-2)` m
=1.5747 m
