A thin rod of length 1 m is fixed in a vertical position inside a train, which is moving horizontally withconstant acceleration 4 m/s2. A bead can slide on the rod, and friction coefficient between them is 1/2.If the bead is released from rest at the top of the rod, find the time when it will reach at the bottom. Solution) If mass of bead is m;mg-µN=maNow, N=pseudo force due to acceleration of train, which is equal to 4m Newton. => mg-µ(4m)=ma=> g-4µ=a=> a=8ms-2 Using, second equation of motion:1=0.5(8)t2T=0.5sec
A cyclist rides at a constant speed of 12.0 m/s for 1.20 min and then coasts to a stop with uniform acceleration 21.2 s later. If the total distance travelled is 1321 m, then w
Roche limit: The position about a massive body where the tidal forces because of the gravity of the primary equivalent or exceed the surface gravity of a particular satellite.
The driver of an SUV slammed on the breaks when he saw a tree 52 m away blocking the road. The SUV slowed down at a constant rate of 4.0 m/s2 for 3.6 s before reaching the tree. Wh
Define Eddy Currents ? If you try to pull a solid piece of some metals (good electrical conductors) quickly between the poles of a strong magnet, you will feel a force pushing
