1st Equation of Motion
- None of these
A car is travelling with a constant speed of 5 m/s. suddenly superman comes and starts pushing from behind providing a constant acceleration of 5 m/s2. Find the velocity of the car after 2 sec.
Car A is moving with a speed of 36 km/h on a two-lane road. Two cars B and C, each moving with a speed of 54 km/h in opposite directions on the other lane are approaching car A. At a certain instant when the distance AB = distance AC = 1 km, the driver of car B decides to overtake A before C does. What must be the minimum acceleration of car B so as to avoid an accident?
A car moving at a speed u is stopped in a certain distance when the brakes produce a deceleration a. If the speed of the car is nu, what must be the deceleration of the car to stop it in the same distance?
Which of the following displacement time (x-t) graphs can possibly represent the one-dimensional motion of a particle?
A car accelerates from rest at a constant rate α for some time after which it decelerates at a constant rate β to come to rest. If the total time elapsed is t, the total distance travelled by the car is given by
- 85 m/s2
- 65 m/s2
- 55 m/s2
- 145 m/s2
