OK, so using the kinematic equation I've found the acceleration to be 15.87 m/s^2...do I use another kinematic equation to find a velocity, and use F=ma with the mass of the box (6.1kg) and my acceleration (15.87) to get a force of 96.81N, then multiply that by the velocity for power? Or do I...
Homework Statement
A 6.1-kg box is being lifted by means of a light rope that is threaded through a single, light, frictionless pulley that is attached to the ceiling.
(a) If the box is being lifted at a constant speed of 2.0 m/s, what is the power delivered by the person pulling on the...
Homework Statement
A 78.4-kg airplane pilot pulls out of a dive by following, at a constant speed of 162 km/h, the arc of a circle whose radius is 321.0 m. At the bottom of the circle, he is accelerating at 6.31 m/s upwards. What is the force exerted on the pilot by the airplane seat...
Homework Statement
A curve of radius 16 m is banked so that a 940 kg car traveling at 44.4 km/h can round it even if the road is so icy that the coefficient of static friction is approximately zero. You are commissioned to tell the local police the range of speeds at which a car can travel...
Homework Statement
In the time interval from 0.0 s to 10.8 s, the acceleration of a particle traveling in a straight line is given by ax = (0.1 m/s3)t. Let to the right be the +x direction. The particle initially has a velocity to the right of 10.0 m/s and is located 4.8 m to the left of the...
