# A particle travels along a straight line from a point A on the line. Its velocity after t seconds is (48-3t)cm/s. If its distance from A after t seconds is s cm, find s in terms of t. Hence find the time that elapses before the particle is back again at A. 0

### Faq

Mathematics 16 s

Step-by-step explanation:

Given:

s = su = 0v = 48 - 3ta = t = t

Substituting values into SUVAT formula to find s in terms of t:    To find the time that elapses before the particle is back at A, set s to zero and solve for t:      Therefore, t = 0 and t = 16, so the time that elapses before the particle is back again at A is 16 s

Mathematics

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in$1800 sales

Here,

tip=18%of $32 tip=(18/100)*32 =0.18*32 =$5.76

Total payment=32+5.76=\$37.76

Mathematics

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
