Question

A car is moving with a uniform velocity of 10m/s.The driver of the car decides to overtake a bus moving ahead the car.So, the driver accelerates at 20 m/s for 10 seconds.Find the velocity of the car at the end of 10 seconds and also find the distance travelled by the car while accelerating

Answer 1

u = 10m/sec
t = 10sec
a = 20m/sec²
v = ??
s = ??

v = u + at
v = 10 + 20×10
v = 210m/sec

Now,

s = ut + 1/2at²

= 10×10 + 1/2×20×100

= 1100m
