- You place a crate of mass 25.1 kg on a frictionless 3.17-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.32 s after you released it. What is the angle of the incline? 25.1 degrees 21.8 degrees 28.3 degrees 36.8 degreesYou are designing a high-speed elevator for a new skyscraper. The elevator will have a mass limit of 2400 kg (including passengers). For passenger comfort, you choose the maximum ascent speed to be 18.0 m/s, the maximum descent speed to be 10.0 m/s, and the maximum acceleration magnitude to be 3.40 m/s 2. Ignore friction. What is the minimum time it will take the elevator to ascend from the lobby to the observation deck, a vertical displacement of 640 m?A block with mass m = 14.9 kg slides down an inclined plane of slope angle 18.8o with a constant velocity. It is then projected up the same plane with an initial speed 2.95 m/s. How far up the incline will the block move before coming to rest?
- A hot air balloon begins to rise from rest. The lift on the balloon due to the buoyant force is 5000 N. In order to minimize the time until the passenger is reunited with their cell phone, what should the horizontal component of the passenger’s velocity be so that they land directly on their phone which is initially 3 m away in the horizontal direction?a block of mass m = 10.2 kg sitting on a ramp that makes an angle θ = 21° with the horizontal. This block is being pushed by a horizontal force F = 212 N. The coefficient of kinetic friction between the two surfaces is μ = 0.49. Write an equation for the acceleration of the block up the ramp using variables from the problem statement together with g for the acceleration due to gravity. Find the acceleration of the block up the ramp in m/s2.At t = 0.00 s a ball is started rolling up an inclined plane with an initial velocity of 6.00 m/s, 15.0°. At t = 2.00 s the ball reverses its direction and begins to roll back down. (a) How far up the slope does the ball travel? (b) Find the ball's acceleration. (c) Find the speed of the ball at t = 3.00 s. (d) Find the distance traveled by the ball during these 3.00 seconds. (e) Find the ball's position at t = 3.00 s.

(2) Compute the angle that the string makes with the vertical.A block of mass 4.6 kg is sliding down a ramp with an initial speed of 1.5 m/s. The ramp is inclined from the horizontal by an angle theta = 34.9 degrees and the coefficient of kinetic friction is uk = 0.73. What is the magnitude of the displacement of the block along the ramp from the initial time until it stops?A particle of mass 1.05 kg is subject to a force that is always pointed towards the East but whose magnitude changes linearly with time t. The magnitude of the force is given as F = 4t, and has units of newtons. Let the x-axis point towards the East. Determine the change in x-coordinate in meters of the particle Δx between t = 0 and t = 2.4 if the initial velocity is 17.5 m/s, and pointed in the same direction as the force.
