Question

the initial velocity of a body moving along a straight line is 7 m/s it has a uniform acceleration of 4 m/s ^2 what is the distance covered by the body in the 5 the second of its motion ?

Answer 1

Answer:

25m Is The Answer

Explanation:

Given,

u=7m/s

a=4m/s  

n=5

The distance covered by the body in n  sec is given by

Sn=u+3/2(2n-1)

S5=7+4/2(2*5-1)

S5=25m

The amplitude of a periodic variable is a measure of its change in a single period. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values. In older texts, the phase of a period function is sometimes called the amplitude
