Question

A car is moving with a speed of 108 km/hr on a circular path of radius 500 m .Its speed is increasing at the rate of 2m/s what is the acceleration (a) 9.8 m/s2 (b) 2.7 m/s2 (c) 3.6 m/s2 (d) 1.8 m/s2​

Answer 1

Answer:

2.7m/s²

Answer 2

Answer:

Correct option is

D) 2.7 m/sec²

Tangential acceleration: a^t = 2m/s²

Centripetal acceleration:a^r = v²/r

= 900/500

=1.8m/s²

∴ Net acceleration =√(2² + (1.8)²)

=2.7m/s²
