- A 2100 kg truck has put its front bumper against the rear bumper of a 2400 kg SUV to give it a push. With the engine at full power and good tires on good pavement, the maximum forward force on the truck is 18,000 N. What is the maximum possible acceleration the truck can give the SUV? At this acceleration, what is the force of the SUV's bumper on the truck's bumper?arrow_forwardCommercial airplanes are sometimes pulled out of the passenger loading area by a tractor. a) An 1800 kg tractor exerts a force of 1.75 × 104 N backward on the pavement, and the system experiences forces resisting motion that totals 2400 N.

- When an airplane is in level flight, its weight is balanced by a vertical “lift,” which is a force exerted by the air. How large is the lift on an airplane in such flight if the mass of the airplane is 1.20 x 103 kg? Draw a free body diagram of the airplane.arrow_forwardA student attaches a bucket to a cart resting on a 15° incline. The different force acting on the objects are: T: Tension of the strings; N: Normal Force; f: any possible friction; W1: weight of cart; and W2: weight of bucket cart T T bucket fk 15° V W1 67.
