Q1. You're driving down the highway late one night at 20 ;{rm m/s} when a deer steps onto the road 35;{rm m} in front of you. Your reaction time before stepping on the brakes is 0.50 ;{rm s}, and the maximum deceleration of your car is 10;{rm m}/{rm s}^{2}.
Q2. The leg and cast weigh 220 N. find out the weight and the angle needed so that no force is exerted on the hip joint by the leg plus the cast.
What is an angular acceleration
What minimum horsepower must a motor have to be capable to drag a 290 box along a level floor at a speed of 1.05 if the coefficient of friction is 0.50.
If a disco disk is rotating with a person on it on the outer side, then if he moves inside (towards the center), the angular velocity will change-How will the energy be conserved.
After the collision, the 2.00-kg object has a velocity 5.00 m/s to the west. How much kinetic energy was lost throughout the collision.
What would be the radius of curvature of the cornea
What friction torque is necessary to reduce its angular speed from 90.0 {rm rpm} to 45.0 {rm rpm} in a time interval of 32.0 {rm s}.
Uniform rate of acceleration
Illustration on Eratosthenes' process
A uniform plank of length 5.9 m and weight 212 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support .To what distance x can a person who weighs 443 N walk on overhanging part of the plank before it just begins ..
If the 2 kg mass slides on a horizontal frictionless surface, what is the speed of the mass 4 kg while it has fallen a distance 0.4 m downward from its rest position.
Establish the initial volume of the gas . What is the magnitude of normal force that each brake pad applies to the rim.
Two identical spacecraft are to be accelerated by rockets. The first rocket fires with a force 4 times as large as that of the second rocket. The acceleration of the first rocket is how many times as vast as the acceleration of the second rocket.
