Step 1
For the 30.0 kg mass, the force due to gravity is acting downwards and is equal to (30.0 kg)(9.8 m/s^2) = 294 N. For the 10.0 kg mass, the force due to gravity is acting downwards and is equal to (10.0 kg)(9.8 m/s^2) = 98 N. (a) Show more…

Two masses of $3.00 \mathrm{~kg}$ and $5.00 \mathrm{~kg}$ are connected by a light string that passes over a frictionless pulley, as was shown in Figure $5.15 \mathrm{a}$. Determine (a) the tension in the string, (b) the acceleration of each mass, and (c) the distance each mass will move in the first second of motion if they start from rest.

An object with mass $m_{\mathrm{L}}=$ $5.00 \mathrm{~kg}$ rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass $m_{2}=10.0 \mathrm{~kg}$, as shown in Figure P4.36. Find the acceleration of each object and the tension in the cable.
