Two stunt drivers drive directly toward each other. At time t=0 the two cars are a distance D apart, car 1 is at rest, and car 2 is moving to the left with speed v0. Car 1 begins to move at t=0, speeding up with a constant acceleration ax. Car 2 continues to move with a constant velocity.
At what time do the two cars collide?
Assume a 64 kg boy and a 42 kg girl use a mass less rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3 m/s2, find out the magnitude of the acceleration of the boy toward girl.
A block of weight 43.6 N is hanging from a rope. The tension from the rope is pulling upward on the block. The block is accelerating upward at a rate of 1.22 m/s^2. What is the magnitude of the tension in the rope?
Illustrate what is the maximum vertical displacement that he ball reaches during its trajectory?
Two spherical objects have a combined mass of 200. The gravitational attraction between them is 8.01×10-6 while their centers are 21.0 apart.
An Atwood machine consists of two masses, = 7.1 and = 8.7 , linked by a cord that passes over a pulley free to rotate about a fixed axis. The pulley is a solid cylinder of radius = 0.40 and mass 0.70 .Determine the magnitude of the acceleration of..
A positive particle with charge 2Q is at the origin between two equal negative particles each with charge - Q, Draw an electric field line diagram of the three paricle system
An electric field of 7.85 10^5 V/m is desired between two parallel plates, each of area 42.0 cm2 and separated by 2.45 mm of air. What charge must be on each plate.
From then on, the wheel turns through an angle of 431 rad as it coasts to a stop at constant angular deceleration. Illustrate a t what time does the wheel stop?
A lead ball is dropped into a lake from the diving board 30 m above the water. After entering the water, it sinks to the bottom with the constant velocity equal to velocity with which it hit the water. The ball reaches the bottom 10 s after it is ..
The loaded cab of an elevator has a mass of 3.6 x 10^3 kg and moves 193m up the shaft in 20s at constant speed. At what average rate does the force from the cable do work on the cab.
A 55.6 kg child slides down a water slide with a velocity of 0.9 m/sec at the top. At the bottom of the slide, she is moving horizontally, y=1.5 meters above the water. She splashes into the water d=2 meters to the left of the bottom of the slide.
At each of the designated points, rotate the given vector to indicate the direction of the force exerted by the water on either the inside of fishbowl (for points A and B) or the outside of the goldfish (for points C, D, and E).
