4. A drag racing car's engine produces 12,000 Newtons of thrust, pushing the car forward down the track. Frictional forces resist the forward motion of the car witha total backward
force of 2010 Newtons. If the mass of the car is 820 kg, what is the acceleration of the
vehicle?

An 820 kg car that experiences a 12,000 N force forward and a 2,010 N force backward has an acceleration of 12.2 m/s².

A car experiences a 12,000 N force that pushes it forward and a 2,010 N force that pushes it backward. The net force (F) acting on the car is the difference between both forces.

F = 12,000 N - 2,010 N = 9,990 N

An 820 kg (m) car experiences a net force (F) of 9,990 N. We can calculate the acceleration (a) of the vehicle using Newton's second law of motion.

$F = m \times a \\\\a = \frac{F}{m} = \frac{9,990N}{820kg} = 12.2m/s^{2}$

An 820 kg car that experiences a 12,000 N force forward and a 2,010 N force backward has an acceleration of 12.2 m/s².

Answer from: Arealbot

Acceleration, a = 12.18 m/s²

Explanation:

Given the following data;

Forward force = 12000N

Backward force = 2010N

Mass = 820kg

First of all we would find the net force.

Since the forces are acting in opposite direction, we would subtract the values of the forces.

Net force, F = Forward force - Backward force

Net force, F = 12000 - 2010

Net force, F = 9990N

Now, to find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

F = ma

Where;

F represents force.m represents the mass of an object.a represents acceleration.

Making acceleration (a) the subject, we have;

$Acceleration (a) = \frac{F}{m}$

Substituting into the equation;

$Acceleration (a) = \frac{9990}{820}$

Acceleration, a = 12.18 m/s²

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
