At a college homecoming 20 students lifted a sports car. each student exerted 450n of upward force on the car. a) what is the mass of the car in kg? b) what is its weight in lbs?

(a) 918.37 kg

(b) 2020.41 lbs

Explanation:

number of students = 20

Force of each student = 450 N

Total upward force = 450 x 20 = 9000 N

(a)

Let m be the mass of car

F = m x g

9000 = m x 9.8

m = 918.37 kg

(b)

As we know that, 1 kg = 2.20 lbs

So, 918.37 kg = 2.20 x 918.37 = 2020.41 lbs
