A car is travelling along a circular curve that has a radius of `50m` . If its is speed is `16m//s` and is increasing uniformly at `8m//s^(2)` . Determine the magnitude of its accleration at this instant.

Text Solution

Verified by Experts

The correct Answer is:
B
`a_(t)=8m//s^(2)`
`a_(r)=(v^(2))/(R)=(16)^(2)/(50)=5.12m//s^(2)`
`a=sqrt(a_(t)^(2)+a_(r)^(2))=9.5m//s^(2)`
