Josh's office door is 0.82 m wide, 6.0 cm thick, and 2.10 m high. The door has a mass m = 15.0 kg and pivots on frictionless hinges. A door closer is attached to the door and the top of the door frame. When the door is open and at rest, the door closer exerts a torque Γ = 4.50 N m. What is the smallest force that you need to apply to the door to hold it open? Enter your...

A projectile is launched from the top of a cliff at an angle of 45 degrees and with a velocity of 600 m/s. See Figure 1. What will be the height of the projectile at a distance of 1500 m from the launch point? What will be the distance, d1, from the launch point when the projectile will have a velocity vector at an angle of 60 degrees below the horizontal?
