How much energy is required in changing the velocity of an object of mass 5000kg from 20ms to 30ms?
Initial kinetic energy = 1/2 M Vi2 Final kinetic energy = 1/2 M Vf2 Difference = 1/2 M (Vf2 - Vi2) = 2,500(302 - 202) = 2,500(900 - 400) = 2,500 x 500 = 1,250,000 joules
If a projectile is fired straight up in the air at a speed of 30ms the total time to return to its starting point is about?
not enough information to support it
When body have 2ms accleration in 15 seconds with a velocity 30ms does the velocity of the car uniform?
Although the question is stated in a somewhat confusing way, we can state withconfidence that the velocity of the car is NOT uniform, because a value is given forits acceleration. 'Uniform' motion means zero acceleration.
What is a story problem for acceleration?
Jack is driving a car. As he passes post 1 he is travelling at 15ms-1 and starts to accelerate at a steady speed. 8 seconds later he passes post 2 travelling at 30ms-1. Post 1 and 2 are What is his acceleration during this time?
A car accelerates from rest and accelerates at 3 ms-2 how long it will take to reach a velocity of 30ms-1?
Acceleration = (change in speed) / (time for the change)3 = (30) / (time)3 x (time) = 30time = 30/3 = 10 seconds

A car is travelling at 30ms driver sees a danger ahead sign and does an emergency stop reaction time is 0.6s calculate how far the car travels before the driver starts to press the brake pedal?
Your answer is 18 meters 30 * 0.6 = 18
A car is moving at a constant speed of 30ms the combined mass of the car and the driver is 1000kg if the driving force is 3000N what is the value of the frictional force?
If the car and driver are moving (along a flat horizontal surface) at constant speed, then there is no acceleration, and the net horizontal force is zero.The applied 3,000N must be canceled by an effective total 3,000N of friction.

A 500kg truck moving at 30ms strikes a parked 300kg car they connect together and move forward what is the speed of the car and truck as they move forward connected together after the collision?
A Lot!
How far can a xbox 360 wifi reach?
The new wireless N adapter for Xbox 360 can work effectively from 50-100 feet, however, there is some notable lag-time of about 20-30ms.
Can a thin man put on weight by using protein and working out?
Hello im 14 nd thin I work out for about 30ms a day and eat good but it doesn't seem like I'm gaining musle should I use protein
A 500kg truck moving a 30ms strikes a parked car and they connect together and move forward what is the speed of the car and truck as they move forward connected together?
Momentum = mass x velocity. You already stated the mass and velocity so you can figure out the momentum.
How long does take to read a disk with 800 cylinders each containing 5 tracks of 32 sectors?
we have seek = 10-50 ms so , average seek = (10+50) / 2 = 30ms and the access time = seek + latency = 20 + 30 = 50 ms
