A train slows down as it rounds a sharp horizontal turn, going from 88.0 km/h to 56.0 km/h in the 13.0 s that it takes to round the bend. The radius of the curve is 160 m. Compute the acceleration (both magnitude and direction) at the moment the train speed reaches 56.0 km/h. [Assume the train continues to slow down at this time at the same rate.]
Cumulative Problem 1 A 150.0-kg crate rests in the bed of a truck that slows from 56.0 km/h to a stop in 12.0 s. The coefficient of static friction between the crate and the truck bed is 0.675. 1) Will the crate slide during the braking period? The crate will slide during the braking period. The crate will not slide during the braking period. Submit 2) What is the minimum stopping time for the truck in order to prevent the...
A 1500kg truck slows down from a speed of 25m/s to a complete stop over 3.0s. What is the average force that the brake pads must exert on the truck to complete this motion?
A train slows down at a constant rate as it rounds a sharp circular horizontal turn. Its initial speed is not known. It takes 16.4 s to slow down from 72 km/h to 27 km/h. The radius of the curve is 161 m. As the train goes around the turn, what is the magnitude of the tangential component of the acceleration? Answer in units of m/s^2. As the train goes around the turn, what is the sign of the tangential...
A motorboat traveling on a straight course slows uniformly from 70 km/h to 30 km/h in a distance of 60 m . What is the magnitude of the boat’s acceleration?
A 2400 kg truck traveling north at 36 km/h turns east and accelerates to 55 km/h. (a) What is the change in the truck's kinetic energy? (b) What is the magnitude of the change in its momentum?
A 1760 kg truck traveling north at 33 km/h turns east and accelerates to 54 km/h. (a) What is the change in the truck's kinetic energy? (b) What is the magnitude of the change in its momentum? I only need part B but if A helps you to solve it.
(a) What is the kinetic energy in joules of a 960-kg automobile traveling at 76 km/h? J (b) How much work would have to be done to bring a 960-kg automobile traveling at 76 km/h to a stop? J
(a) What is the kinetic energy in joules of a 1120-kg automobile traveling at 78 km/h? J (b) How much work would have to be done to bring a 1120-kg automobile traveling at 78 km/h to a stop? J
A car traveling 70 km/h slows down at a constant 0.47 m/s2 just by "letting up on the gas." Calculate the distance it travels during the fifth second. Express your answer to two significant figures and include the appropriate units.
