Q2. A particle moves with constant acceleration a. The expression v1+at represents the particle's velocity at what instant in time?
Find (a) magnitude and (b) direction of A - B. (Give the direction as a positive angle with respect to due east). Find out the (c) magnitude and (d) direction of B - A. (Give the direction as a positive angle with respect to due west).
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.
David is driving a steady 21.0 when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.70 at the instant when David passes. How far does Tina drive before passing David.
A 40 g rifle bullet travelling 260 m/s buries itself in a 4.0 kg pendulum hanging on a 3.0 m long string, which makes the pendulum swing upward in an arc. Find out the vertical and horizontal components of pendulum's displacement.
Write down the expression for net torque
A gun shoots bullets that leave the muzzle with a speed of 336 m/s. If a bullet is to hit a target 136 m away at the level of the muzzle, the gun has to be aimed at a point above the target. How far above the target is this point.
What centripetal force does an 80-kg passenger experience when seated 12 m from the center of the Ferris wheel whose angular speed is 0.50 rad/s.
What is an average number of ozone molecule
Assume that you need to get a heavy couch into the bed of a pickup truck. You know the bed of the truck is at the height of 1.00 and you require a ramp that makes an angle of 40 with the ground if you are to be able to push the couch.
Illustrates the difference between acceleration and velocity
One displacement vector A has magnitude of 2.78 km and point due north. Another displacement vector B has a magnitude of 7.40 km and also points due north. Provide diagrams and calculate the magnitude and direction of A+B, B-A, A-B.
Two small insulating spheres with radius 4.00×10-2 are separated by a large center-to-center distance of 0.595. One sphere is negatively charged, with net charge -2.40, and the other sphere is positively charged, with net charge 3.70. The charge i..
