Q1. A platform is rotating with the angular speed of 3.20 rad/s and an angular acceleration of 11.2 rad/s2. At a point on the platform that is 1.30 m from the axis of rotation, what is the magnitude of the total acceleration a?
Q2. A 0.449 kg ice puck, moving east with a speed of 2.91 m/s, has the head-on collision with a 0.846 kg puck initially at rest. Assume a perfectly elastic collision, what will be the speed and direction of each object after the collision?
Two identical carts travel at 1m/s in opposite directions on a common horizontal surface. They collide head-on and are reported to rebound, each with the speed of 2m/s.
Calculate the pressure at the center of pipe A. Suppose T = 10?C.
a) Determine the magnitude and direction of the electrostatic force acting on particle A in the figure given below due to particles B and C . The values of the charge on these particles are indicated in the figure.
Examine whether it is reasonable to ignore the effects of gravity for each particle. Evaluate the paths travelled by electron and proton and explain the differences.
What mass of water at 29.0°C added to a Styrofoam cup containing two 60.0 g ice cubes from a freezer at -16.0°C will result in a final temperature of 5.00°C for the drink? Explain it.
Find out how fast a GPS satellite is moving relative to someone on the ground and from that how much slower time runs where it is in orbit relative to someone on the ground.
