- Two blocks are joined by an inextensible cable as shown. If the system is released from rest, determine the velocity of block A after it has moved 2 m. Assume that the coefficient of kinetic friction between block A and the plane is 0.25 and that the pulley is weightdess and frictionless. 200 kg ㄱ 300 kg A BPlease tapy answerA 1700 kg car is driving down a highway at a constant velocity when a deer jumps out onto the road 59.6 m ahead. The coefficient of friction between the car tires and the road is 0.21. Calculate the initial velocity of the car if it is able to stop just before hitting the deer. (You do not need to account for reaction time of the driver. Assuming the car is breaking the entire 59.6 m distance and that friction is the only force stopping the car.) v0 = m/s
- In the movie The Rocketeer, a teenager discovers a jet-powered backpack in an old barn. The backpack allows him to fly at incredible speeds. In one scene, however, he uses the backpack to rapidly accelerate an old pickup truck that is being chased by “bad guys.” He does this by bracing his arms against the cab of the pickup and firing the backpack, giving the truck the acceleration of a drag racer. Is the physics of this scene “Good,”“Bad,” or “Ugly?” Draw and Explain.A 60 kg skier starts from rest at a height H = 33 m above the end of a ski jump ramp. If the skier leaves the ramp at an angle of θ = 25º, determine the maximum height h the skier will reach.Problem 4.17 7 of 11 Can cars "stop on a dime"?
