What does the path of an object look like when it is in uniform motion?
During an experiment, a signal from a spaceship reached the ground station in five minutes. What was the distance of the spaceship from the ground station? The signal travels at the speed of light, that is, 3 × 108m s−1.
Arrange the following speed in increasing order (keeping the least speed first):
An athlete running with a speed of 10 m/s.
One of the following is not a vector quantity. This one is :
The speed of a car is 72 km h-1. Express it in m s-1.
Express the following in m s−1.
1 km h−1
A car is moving with a velocity 20 m s-1. The brakes are applied to retard it at a rate of 2 m s-2. What will be the velocity after 5 s of applying the brakes?
Figure shows the displacement of a body at different times .
Calculate the average velocity during the time interval 5 s to 9 s ,
[Hint : From 5 s to 9 s , displacement = 7 m - 3m = 4m]
A speeding car changes its velocity from 108 kmh−1 to 36 kmh−1 in 4 s. Calculate its deceleration in
- ms−2
- kmh−2.
Which of the following figures (Fig. 8.3) represents uniform motion of a moving object correctly?
