A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 106 N. The mass of the rocket is initially 2.00 x 105 kg. What is the initial acceleration of the rocket, assuming you can neglect air resistance?

A block with mass m1 = 8.5 kg is on an incline with an angle θ = 33° with respect to the horizontal. The spring is replaced with a massless rope that pulls horizontally to prevent the block from moving. What is the tension in the rope?

Particle physicists have identified a type of fundamental particle called a muon, which effectively behaves like a very heavy electron. Imagine a muon of mass 1.88 × 10-28 kg is observed in a particle accelerator. It has an initial speed of 3.50 × 105 m/s. It moves in a straight line, and its speed increases to 1.25 × 106 m/s in a distance of 75.0 cm. Assume that the acceleration is constant. Find the magnitude of the force exerted on the muon.

A steam catapult applies a very large force to supplement the engine thrust of a jet fighter as it takes off from an aircraft carrier. The jet has a mass of 3850 kg ad must reach its take off speed of 75 m/s at the end of the 208 m fight deck. What is the combined force of the catapult and engines?

A boat has a mass of 6769 kg. Its engines generate a drive force of 4039 N, due west, while the wind exerts a force of 800 N, due east, and the water exerts a resistive force of 1246 N due east. What is the magnitude of the boat's acceleration?

A paratrooper with a fully loaded pack has a mass of 119 kg. The force due to air resistance on him when falling with an unopened parachute has magnitude FD = bv2, where b = 0.13 (N s2)/m2. The force of air resistance acting on him is 516N up. What is his acceleration?

Blocks with masses of 1.0 kg, 2.0 kg, and 3.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 12 N force applied to the 1.0 kg block. How much force does the 2.0 kg block exert on (a) the 3.0 kg block and (b) the 1.0 kg block?

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

If the only forces acting on a 5-kg mass are F1 = (2i- 3j) N and F2 = (6i + 8j) N, what is the magnitude of the acceleration of the particle?

Two teams of nine members each engage in a tug of war. Each of the first team's members has an average mass of 68 kg and exerts an average force of 1350 N horizontally. Each of the second team's members has an average mass of 73 kg and exerts an average force of 1375 N horizontally. (a) What is the acceleration (in m/s? in the direction the heavy team is pulling) of the two teams? 0.18 v m/s? in the direction the heavy team is pulling (b) What is the tension (in N) in the section of rope between the teams? 12639.6 X N
