Show major steps and formulas involved!!!!, this is a test review, only need the answered to compare with mine...thanks!!! 3. A 10 kg block is hanging from a solid cylinder of mass 20 kg (R = 3m). The block is attached by a rope that winds around the cylinder and is 4 m above the ground. M2 = 20 kg R = 3 m M1 = 10 kg 4 m a. Calculate the acceleration of the block. b. How much...
Show major steps and formulas involved!!!!!, this is a test review!!!!,Please really need to undertand the logic on how you got the answeres!!!Thanks!!! 5. A man (m2 = 30 kg) is standing on scaffold (m1 = 150 kg). There is a bucket on the other side of the scaffold 2 m form the edge. m2 = 30 kg m3 = 2 kg m1 = 150 kg 5 m What is the tension on the ropes holding up the scaffold?
Show major steps and formulas involved, please!!!! 4. Calculate the center of gravity of the following masses. 5 m 10 m M1 M2 8 m 4 m M3 M1 = 10 kg M2 = 20 kg M3 = 30 kg
Consider two masses sliding across a frictionless surface about to undergo a head-on collision as shown in the figure. The first mass (m1 = 3 kg) is travelling to the right with a speed of V1 = 8 m/s. The speed of the second mass (m2 = 5 kg) is unknown. After the masses collide, m1 rebounds moving off at a speed of v = 2 m/s in the opposite direction, while m2 is motionless. a)(10 pts.) At what velocity,...

A hockey puck (m1=0.4 kg) is sliding along the ice in the +y direction with a speed of v1=5.2 m/s. It collides with curling rock m2=6.7 kg travelling in the +x direction with speed v2 = 0.18 m/s and the two objects stick together. At what angle with respect to the +x axis does the combined object travel after the collision?
Show major steps and formulas involved!!!!!, really need to understand how to get the results, if you can draw a picture, I will appretiate it!!! 89. A 5.00-g bullet mov- AMT ing with an initial M speed of v; = 400 m/s is fired into and passes through a 1.00-kg block as shown in Fig- ure P9.89. The block, initially at rest on a frictionless, horizontal surface, is connected Figure P9.89 to a spring with force constant 900 N/m. The...
Show major steps and formulas involved!!!!!, this is a test review!!!!! 1. Shown here are the graphs for i(t) (given in nA) and v(t) (given in MV). m in $t(ms) t(ms) a.

Show major steps and formulas involved!!!!!, really need to understand how to get the results, if you can draw something about tge picture, I will appretiated!!!!! 80. A small block of mass m = 0.500 kg is released from W rest at the top of a frictionless, curve-shaped wedge of mass m, = 3.00 kg, which sits on a frictionless, hori- zontal surface as shown in Figure P9.80a. When the block leaves the wedge, its velocity is measured to be...
Show major steps and formulas involved!!!!, please really need to understand how to get the results, show how you got them please!!! *-29 SSM WWW In Fig. 8-40, a block of mass m = 12 kg is re- leased from rest on a frictionless incline of angle 0 = 30°. Below the block is a spring that can be compressed 2.0 cm by a force of 270 N. The block momentarily stops when it compresses the spring by 5.5 cm....
