A car travels a distance of 150 m in the direction of a constant force of 50 N. The work done on the car is

the work done on the car is 7,500 J.

Explanation:

Given;

distance traveled by the car, d = 150 m

applied force, F = 50 N

The work done on the car is calculated as;

W = F x d

W = 50 N x 150 m

W = 7,500 J

Therefore, the work done on the car is 7,500 J.

double the distance = divide strength by 4

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
