Question

a motor cyclist staring from rest accelerates at 10m/s -2 for 10 second and travels at a uniform velocity for the next 20 second what is the total distance travelled in this intervals of 30 seckond​

Answer 1

Answer:

the total distance travelled is...

ut+1/2at^2 + v×20..............(1)

then v = u + at = 0 +10×10 = 100m/s

and 1/2×10×100 = 500 m

then total distance covered = 500+20×100 = 2500 m answer..
