Question

Which type of vector quantity can be used to derive the 2nd Equation of motion?

That is s=ut+1/2at^2

Don't use the graphical method​

Answer 1

(ii) Second equation of motion ; We know that the area under the velocity-time graph for a given time interval represents the distance covered by the uniformly accelerated object in that interval of time.

∴ Distance (displacement) travelled by the object in time t is :

S = area of trapezium OSQP

= area of rectangle OSRP + Area of triangle PRQ

S=OS×OP+
