A 100g granite cube slides down a 40 degree frictionless ramp. At the bottom, just as it exits into a horizontal table, it collides with a 200g steel cube at rest. How high above the table should...

A Jet stream of water hits a fixed turbine blade with velocity v. The blade is shaped so that the water bounces back at 180 degrees, directly backwards from its initial direction. If the mass of the...

I need help with this question. Thanks in advance.

What happens to the electric field as you increase the length of a positively charged rod? What to the electric field for a negatively charged rod?

A diver hits the water at a velocity of 17.64 m/s from a 16 m high board. What is the diver's rate of deceleration when the diver reaches a depth of 1.85 m under water?

A car traveling initially at 9.93 m/s acceler- ates at the rate of 0.944 m/s2 for 2.07 s. What is its velocity at the end of the accel- eration?

You re driving parallel to train tracks at 65.0 km/h when a train passes you, going a steady 96.0 km/h. A track crossing is up ahead, so you begin to speed up at 8.00 m/s^2. How far do you drive before...

When a monatomic ideal gas expands at a constant pressure of 5.4 x 105 Pa, the volume of the gas increases by 4.6 x 10-3 m3. Determine the heat that flows. If heat flows into the gas, then the heat...

Two blocks connected by a light horizontal rope sit at rest on a horizontal, frictionless surface. Block A has mass 15.0kg, and block B has mass m. In the first 5.00s after the force is applied, block...

For a disk of radius R = 17 cm and Q = 5 ✕ 10-6 C, calculate the electric field 1 cm from the center of the disk using all three formulas below. Note: ε0 = 8.85e-12 C2/(N·M2). I got c to be 3...
