Here are the solutions to your problems. 1. Calculate the force that produced this acceleration. Step 1: Convert the mass from tons to kilograms. m = 2.3 tons × 1000 kgton = 2300 kg Step 2: Use Newton's second law of motion to calculate the force. F = ma F = (2300 kg) × (5 ms^2) F = 11500 N The force produced is 11500 N. 2. Calculate the force required to stop the car. Step 1: Calculate the acceleration (deceleration) of the car. The car stops, so the final velocity v = 0 ms. v = u + at 0 ms = 25 ms + a(2 s) -25 ms = a(2 s) a = -25 ms2 s a = -12.5 ms^2 Step 2: Use Newton's second law of motion to calculate the force. F = ma F = (2000 kg) × (-12.5 ms^2) F = -25000 N The negative sign indicates that the force is in the opposite direction of the car's motion, which is expected for a braking force. The magnitude of the force required is 25000 N. That's 2 down. 3 left today — send the next one.
