Question

13.A car of mass 1000 kg is moving with a velocity of 10 m/s. If the velocity-time grap
for this car is a horizontal line parallel to the time axis, then the velocity of the car at the
end of 25 s will be:
(a) 40 m/s
(b) 25 m/s
(c) 10 m/s
(d) 250 m/s​

Answer 1

Answer:

velocity of the car will be 10 m/s

It has given that a car of mass , m = 1000 kg moving with a velocity, v = 10 m/s. velocity - time graph for this car is a horizontal line parallel to the time axis. ... i.e., 10 m/s

Answer 2

Answer:

25m/s

Explanation:

velocity of the car = 10m/s

mass of the car, m=1000kg

slope of v-t graph =0

so, velocity Will be constant because horizontal line is parallel to the time axes.

Hence, the velocity will not change .

so velocity =25m/s
