Since every process is elastic or frictionless, the total potential energy must be the same when the colliding and sliding are over, even though the heights may change for each block. Use that fact to compute the final height of the 3kg block, above the horizontal base. That ...

Four point charges are placed at the four corners of a square. Each side of the square has a length L. Find the magnitude of the electric force onq2 due to all three charges q1, q3 and q4 for L = 1 m and all q = 1.55 C. Answer in units of N

Well, assuming the gravity still has a value, named "g" (although the building is infinitely tall and then its value should be zero), the velocity should be, v=-gt take t=2, and you have, v=-2g If you assume g=9.8 m/s^2, then, v=-19.6 m/s. But remember that physically there is...

A 850-kg race car can drive around an unbanked turn at a maximum speed of 61 m/s without slipping. The turn has a radius of 160 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 11000 N on the car. (a) What is the coefficient of ...

A particle moves along a circular path over a horizontal xy coordinate system, at constant speed. At time t1 = 4.90 s, it is at point (5.30 m, 5.30 m) with velocity (2.20 m/s) and acceleration in the positive x direction. At time t2 = 14.0 s, it has velocity (–2.20 m/s) and ...

Two blocks are initially held at rest on 30° frictionless ramps . The 4 kg block is 1.25 m from the base of the ramp and the 3 kg block is 5 m above the base of the ramp. The two blocks are then released and slide down the ramps and onto a frictionless horizontal surface. The ...
