Question

The engine of a car produces a driving force of 5000 N on the car. Resistive forces R also act on
the car, as shown.
R
AN PRIA
Soon 4713
The car has a mass of 800 kg and an acceleration of 1.0 m/s2
What is the value of R?
A
800N
B
4200N
C
5800 N
D
8000N

Answer 1

the car has a mass of 800kg and an acceleration of 1.0 m/s25800

Answer 2

Answer:

B)4200 N(newtons)

Explanation: R is a force so to find out the froce of an object we multiply mass and accelaration F=ma

Since our mass is 800 kg and accelaration is 1.0 m/s²

F=800x1=800

since we have the engine force which will take 5000 Newtons from it we subtract 800 from 5000 resulting in 4200.
