A) Find the x-component of vector a = (9.0 m/s^2, - y direction)
B) Find the y-component of vector a = (9.0m/s^2, -y direction)
A 950-kg car traveling west at 15.0 m/s collides with a 750-kg car traveling north at 20.0 m/s. The cars stick together. Find the speed of the wreckage just after the collision
At the end of the trip she measures the pressure to be 3 105 Pa. Ignoring the expansion of the tires, find out the air temperature inside the tires at the end of the trip.
Daisy throws a rock horizontally with a speed of 12 m/s from a bridge. It falls 2.28 s before reaching the water below. When the rock hits the water it is traveling with what horizontal component of the velocity.
Two point charges, q1 = 2.0 pC and q2 = -2.0 pC, are separated by 5.6 µm. 1) What is the dipole moment of this pair of charges?
A parachutist descending at the speed of 25 m/s loses a shoe at an altitude of 50 m. (Assume the positive direction is upward.)
A child slides down a slide with the 29 degree incline, and at the bottom her speed is precisely half of what it would have been if the slide had been frictionless. Compute the coefficient of sliding between the child and the slide.
A skier (m=55.0 kg) starts sliding down from the top of a ski jump with negligible friction and takes off horizontally. If h = 6.90 m and D = 10.4 m, determine H.
How to find the position and height of an image
At one instant a bicyclist is 28.0 m due east of a park's flagpole, going due south with a speed of 11.0 m/s. Then 24.0 s later, the cyclist is 26.0 m due north of the flagpole, going due east with a speed of 11.0 m/s. For the cyclist in this 24.0 s ..
Charge q is fired through a small hole in the positive plate of a capacitor. If q is a positive charge, does it speed up or slow down inside the capacitor? reply this question using the concept of force.
An 800 g ball moves in a vertical circle on a 1.07-m-long string. If the speed at the top is 5-m/s, after that the speed at the bottom would be 8.18 m/s.
An underwater diver sees the sun 50 degrees above horizontal. How high is the sun above the horizon to a fisherman in a boat above the driver.
