Question

Please help w problem 29

A ball of mass M = 0.250 kg hangs vertically on a dun thread attached to the ceiling of a van that is at rest Calculate the tension in the thread while the van accelerates at a constant rate from rest to a speed of 50 0 mph in S.00 seconds: Along a horizontal road. Up a 15.0^degree slope. Down a 15 0^degree slope. For the system of blocks shown in the diagram, the strings are of negligible mass and the horizontal surface is frictionless. The blocks are all at rest. Calculate the magnitudes of the tensions in the four cords. C_1, C_2, C_3 and C_4. For the system shown in the diagram below, the horizontal surface is frictionless There is no friction between the slab and the block. The pulley is frictionless. The mass M is attached to the slab by a cord of negligible mass. The system is released horn lest and M accelerates downward with an acceleration of magnitude 3.60 m/s^2. Calculate

Explanation / Answer

29)
Let Tension be T1, T2 , T3 , T4 Respectively for C1, C2, C3. C4.

Now,
T1 = 12.0 * 9.8 N
T1 = 117.6 N

T2 * cos(30) = T1
T2 * cos(30) = 117.6
T2 = 135.8 N

T3 = T2 * sin(30)
T3 = 135.8 * sin(30)
T3 = 67.9 N

T4 = T3 = 67.9 N
