During a violent storm, a car is struck by a failing high-voltage wire that puts an excess charge of -850 mircoC on the metal car. a) how much of this charge is on the inner surface of the car? b) how much is on the outer surface of the car?
A student (m= 75 kg) falls freely from rest and strikes the ground. throughout the collision with ground, he comes to rest in a time of 0.040 s. the average force exerted on him by the ground is +18 000 N.
A ball of mass 0.113 kg is dropped from a height of 1.92m above ground. The acceleration of gravity is 9.8m/s^2.Neglecting air resistance find the speed of the ball when it is at a height of 0.812 m above the ground. Answer in units of m/s.
what was the cars original kinetic energy? after the car has stopped, what is the change in temperature of the brakes and wheels?
A 1.70 kg block is released from rest and allowed to slide down a frictionless surface and into a spring. The far end of the spring is attached to a wall.
find the speed of the test charge. find the distance the car travels during this time in m.
Biometric measurements indicate that each hand typically makes up about 1.25% of body weight. What horizontal force should her wrist exert on her hand.
A stream of water strikes a stationary turbine blade horizontally. The incident stream has a velocity of +16m/s whilst the exit has a velocity of -16m/s. mass of water per second that strikes the blade is 30kg/s.find the magnitude of average force ex..
A circular coil enclosing an area of 96 cm2 is made of 199 turns of copper wire. The wire making up the coil has resistance of 3.0 , and the ends of the wire are linked to form a closed circuit.
A heat engine has a maximum possible efficiency of 0.800. If it operates between a deep lake with a constant temperature of 287.0 k and a hot reservoir, what is the temperature of the hot reservoir?
A 78-kg base runner begins his slide into second base when he is moving at a speed of 4.2 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches base.
The distance to the Andromeda Galaxy is estimated at about 2 ´ 106 light years. A light year is distance travelled by light in one year; if the speed of light is 3 ´ 108 m/s, about how far is it from our galaxy to Andromeda? (1 year = 3.15 ´ 107 s..
Besides the gravitational force, a 3.25-kg object is subjected to one other constant force. The object starts from rest and in 1.20 s experiences a displacement of (4.10 - 3.30) m, where the direction of is the upward vertical direction. find out ..
