A car start from rest and cover a distance of 100m in one sec with uniform acceleration its acceleration is
Answers
100= 0×1 + 1/2× a× 1×1
100= 0 + 1/2 ×1 ×a
100×2 = a
a= 200m/s^2
Answer:
s = ut + 1/2 at^2
100= 0×1 + 1/2× a× 1×1
100= 0 + 1/2 ×1 ×a
100×2 = a
a= 200m/s^2 The correct answer
Explanation:
In mechanics, acceleration is the fee of alternate of the velocity of an object with admire to time. Accelerations are vector quantities (in that they have got magnitude and path).The orientation of an object's acceleration is given with the aid of the orientation of the internet pressure performing on that item. The significance of an item's acceleration, as defined through Newton's 2nd law,is the combined effect of two causes:
the internet balance of all external forces performing onto that object — magnitude is at once proportional to this internet ensuing pressure;
that object's mass, relying on the substances out of which it's far made — magnitude is inversely proportional to the object's mass.
The SI unit for acceleration is metre in keeping with 2d squared
as an example, whilst a vehicle begins from a standstill (zero speed, in an inertial frame of reference) and travels in a directly line at growing speeds, it's far accelerating within the path of tour. If the automobile turns, an acceleration takes place closer to the brand new course and modifications its movement vector. The acceleration of the automobile in its modern course of movement is referred to as a linear (or tangential for the duration of round motions) acceleration, the reaction to which the passengers on board enjoy as a force pushing them lower back into their seats. while changing direction, the effecting acceleration is known as radial (or centripetal at some point of round motions) acceleration, the response to which the passengers revel in as a centrifugal force. If the speed of the car decreases, this is an acceleration in the opposite path and mathematically a bad, from time to time called deceleration or retardation, and passengers experience the reaction to deceleration as an inertial force pushing them ahead. Such bad accelerations are frequently done through retrorocket burning in spacecraft. both acceleration and deceleration are dealt with the identical, as they may be each modifications in speed. each of these accelerations (tangential, radial, deceleration) is felt by means of passengers until their relative (differential) velocity are neutralized in connection with the acceleration because of exchange in speed.
