(ml)
5 10 is 20 25
t(s)
1) What is the acceleration of thecyclist?
(positive , negative ,zero, none of these)
II) What is his velocity?
( 20 m/s , 25 m/s, 10 m/s, 15 m/s)
IIT) What is the distance covered by the cyclist in 15 seconds?
(1500m, 2000m, 3000m, 1000m)
Iv)The slope of Velocity-Time graph Indicates
(Displacement, Acceleration, Speed, Distance)
v)Which among the following is a scalar quantity?
(Acceleration, Velocity, Distance, Displacement)​

Answer 1

Answer:

1) There is no change in velocity with time.

The cyclist is moving with a constant velocity, therefore the acceleration=0

2) velocity=20m/s

3) distance=velocity×time

=20×15=300m

4) acceleration

5) distance
