A criminal is escaping across a roof top and runs off the roofhorizontally at a speed of 5.6 m/s,hoping to land on the roof of an adjacent building. Air resistanceis negligible. The horizontal distance between the two buildings isD, and the roof of the adjacent building is 2.0 m below the jumping-off point. Find the maximum value for D.
How much work did movers do (horizontally) pushing a 140{rm kg} crate 10.60 m across a rough floor without acceleration, if the effective coefficient of friction was 0.700.
At t=0 a grinding wheel has an angular velocity of 24.20 rad/s. It has a constant angular acceleration of 24.2 rad/s^2 until a circuit breaker trips at t = 1.2 seconds.
In lab you find that a 1-kg rocksuspended above water wights 10 N. when the rock issuspended beneath the surface of the water , the scale reads8N.
