Question

Suppose that a sled is accelerating at a rate of 2m/s^2. If the net force is tripled and the mass is doubted, then what is the new acceleration of the sled? Study the diagram below and determine the acceleration of the box and its velocity after being pulled by the applied force for 2.0 seconds. A box is pulled at a constant speed of 0.40 m/s across a frictional surface. Perform an extensive analysis of the diagram below to determine the values for the blanks. The 10-kg object is being pulled to the left at a constant speed of 2.5 m/s. Use your understanding of force relationships and vector components to fill in the blank in the following diagram.

3)

let the initial force be F and mass be m

accelration , a = F/m ...(1)

when F' = 3 * F and m' = 2 *m

the accelration , a' = F'/m'

a' = 3 * F /(2*m)

a' = 1.5 * F/m

a' = 1.5 * 2

a' = 3 m/s^2

the new accelration is 3 m/s^2
