Q1. The driver of the speeding empty truck slams on the brakes and skids to a stop through a distance d. On a second trial, the truck carries a load that doubles its mass. What will at the present be the truck's "skidding distance"?
Q2. Barometric pressure in the eye of a hurricane is 0.91atm (27.2 in of mercury). How does the level of the ocean surface under the eye compare with the level under the distant fair-weather region where the pressure is 1.0atm?
If John Glenn weighed 640 N on Earth's surface, a) how much would he have weighed if his Mercury spacecraft had (hypothetically) remained at twice the distance from centre of Earth? b) Why is it said that an astronaut is never truly "weightles".
How far would trampoline stretch if the performer stands still on it while taking a bow.
Compute the heat absorbed by the gas and work done by the gas during expansion.
Travelling at a speed of 17.10 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.740. What is the speed of the automobile after 1.81 s have el..
Obtain a relation between the equilibrium lattice distance
A solid cylinder of radius 0.35 m is released from rest from a height of 1.8 m & rolls down the incline as shown. Find the angular speed of the cylinder when it reaches the horizontal surface?
Define the frequency components of an AM signal and draw the AM signal for the given modulation index.
Find out the resulting values of the processional rate
An 8.70 block slides with an initial speed of 1.56 down a ramp inclined at the angle of 23.6 with the horizontal. The coefficient of kinetic friction between the block and the ramp is 0.69.
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.
Two horizontal forces, 218 N and 157 N, are exerted in opposite directions on a crate. What is the net horizontal force on the create? Be sure to indicate the direction of the net force. (Assume that the 218 N forces are in the positive direction.)
A proton is travelling to the right at. It has a head-on perfectly elastic collision with a carbon atom. The mass of the carbon atom is 12 times the mass of the proton. What are the speeds of each after the collision? What is the direction of the pro..
