How much work must be done on a kg sled to increase its speed from 10ms to 15 ms?
To calculate the work done on the sled to increase its speed, you need to know the initial and final kinetic energy. The work done is equal to the change in kinetic energy, which is given by the formula: Work = (1/2) * m * (vf^2 - vi^2) Substitute the mass of the sled, initial speed, and final speed to find the work done.
Is initial speed is always zero?
Bob sed Shirley's initial speed is eight million mph
If a car is speeding up its initial speed is what than its final speed?
If a car is speeding up, its initial speed is less than its final speed. As the car accelerates, its speed increases over time, so the initial speed is lower than the final speed attained during acceleration.
How do you find final speed if acceleration time and initial speed is given?
You can find the final speed using the formula: final speed = initial speed + (acceleration * time). Simply plug in the values for initial speed, acceleration, and time to calculate the final speed of the object.
What will be range of projectile if its initial speed is doubled?
Doubling the initial speed of a projectile will quadruple its range, assuming all other factors remain constant. This is because the range of a projectile is directly proportional to the square of its initial speed.
What is initial speed?
initial speed means first
What is the definition of initial speed?
Initial speed is the original, beginning speed of an object.

A ball is thrown straight up with an initial speed of 20 m calculate its initial speed take g10 ms-2?
Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!
How do you work out height from initial velocity final velocity mass and work done?
If you throw an object up, and assume that air resistance is negligible, knowing the initial velocity is enough. One way to do this is to use conservation of energy. Calculate the energy from the initial velocity, then insert it in the formula for gravitational potential energy.Same for final velocity - the final speed is the same as the initial speed. If you know the work done, you already have the first half of the above steps solved.
Can you say initial speed and final speed?
Yes.
If a car is speeding up its initial speed is than its final speed?
If a car is speeding up, it's initial speed is LOWER than it's final speed.
How do you find the time given only the distance and the initial and final velocity?
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
What is the beginning speed of a truck called?
I think its initial speed
