A force accelerates a body of mass M. A second body requires twice as much force...
A particle of mass m1 accelerates at 4.50 m/s2 when a force F is applied. A second particle of mass m2 experiences an acceleration of only 1.35 m/s2 under the influence of this same force F. (a) What is the ratio of m1 to m2? (b) If the two particles are combined into one particle with mass m1 + m2, what is the acceleration of this particle under the influence of this force F?
Apply the free-body diagram for body M and apply Newton's second law considering the kinetic friction force. b. Apply the free-body diagram for the body m, apply Newton's second law. c. Combine the expressions obtained in part a and b to obtain the final equation. d. By graphing applied force versus acceleration we obtain that the equation that best fits the points is y = 0.934x + 0.0645. Determine how much is the total mass of the system and the...
Q2. One car has twice the mass of a second car, but only 1/3 as much kinetic energy. When both cars increase their speed by 6 m/s they then have the same kinetic energy. What were the original speeds of the two cars?

A mass pulled by a constant force accelerates from 10 cm/s to 40 cm/s in 5.5 s. A second force accelerates the same mass from rest to 140 cm/s in 15.5 s. If the first force is known to be 3.5 N, that what is the magnitude of the second force?
A plane is experiencing a constant force and accelerates at 6 50 m/s^2. what will the acceleration be of an object that is half the mass of the plane?
6) Jack accelerates a 7.2 m/s. He jumps with a vertical velocity of 6.8 m/s. There is a 5.7 m hole he is trying to jump over. Jack has a mass of 62 kg. a. What is the minimum horizontal velocity Jack has to be traveling at to clear the hole? b. How much of a run-up does Jack need to achieve this? c. How much force, in a horizontal direction, does Jack exert to produce his acceleration?
A net force of 46 N accelerates a 2-kg mass over a distance of 10 m. (a) What is the work done by this net force? J (b) What is the increase in kinetic energy of the mass? J
Ch. 6, 4 The first car has twice the mass of a second car, but only half as much kinetic energy. When both cars increase their speed by 10 m/s , they then have the same kinetic energy. Part A What were the original speeds of the two cars? Express your answers using two significant figures separated by a comma.
If a force of 25N is applied on a 10kg mass, it accelerates at 1 m/s^2. Find the co-efficient of force between the block and the surface.
