Question

please answer the given question pllz

Answer 1

1.since the slope of the graph is constant therefore acceleration is zero as

a=v1-v2/t1-t2

v1=v2

so

a=0

2.since the body has no acceleration therefore

velocity at 15 sec=velocity at any time=20 m/s

3.distance covered by the cyclist=area under v-t graph

=20*15

=300 m

Hope this helps

Answer 2

Answer:

Explanation:

i). it has no accelaration because it is in constant speed

ii). distance = v x t

15 x 20 = 300m
