A racing car starts from rest and has uniform acceleiation of 5m/sec ^2.If it travels for 20sec ,find the final velocity at this instant

### Asked by jsrashokkumar1978 | 30th May, 2020, 12:10: PM

Expert Answer:

### v = ?
a car starts from rest, u =0
a = 5 m/s^{2}
t= 20 s
first equation of motion is,
v = u + at
v = 0 + 5 x 20
v =100 m/s
Thus, at this instant final velocity is 100 m/s

^{2}
