A 4300-N force from a car s engines produces an acceleration of 3.3 m/s2. What is the mass of the car? A. 4300 kg B. 1300 kg C. 14,000 kg D. 390 kg

Step-by-step answer

P Answered by PhD

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

=4300/3.3

=1303.03kg

Approximately it is aqual to 1300kg

The YMCA lap pool is a right rectangular prism 36.8 long by 20m wide. The pool contains 1472m^(3) of water. How deep is the water

Step-by-step answer

P Answered by PhD

Volume of pool = 1472 m^3

Length = 36.8m

Breadth = 20m

We know,

Volume = l*b*h

1472 = 36.8 * 20 * h

h = 1472/736

h = 2m

Pool is 2m deep
