A CAR OF MASS 800KG ATTAINS A SPEED OF 25M/S IN 20 SECS. THE POWER DEVELOPED IN THE ENGINE IS
A. 1.25 x 104 W B. 2.50 x 104 W ✓ C. 1.25 x 106W D. 2.50 x 106 W The answer to the question is: B. 2.50 x 104 W To calculate the power developed in the engine of a car, we can use the formula: Power = Force × Velocity First, we need to find the force acting on the car. We can use Newton’s second law of motion, which states that force is equal to mass times acceleration: Force = Mass ×…
