A constant net force of 300N is applied to accelerate a cart in a frictionless surface from rest to a velocity of 30 m/s in 5s. What is the mass of the cart? 2. A 0.15 - kg baseball approaches a baseball bat at 30 m/s. If it is in contact with the baseball bat for 0.003 s, what is the average contact force between the ball and the racket? Ignore the air resistance.

Vmax In a laboratory experiment, a sphere of diameter 8.0 mm is released from rest at t = 0 at the surface of honey in a jar, and the sphere's downward speed v when it travels in the honey is found to be given by v = Vmax (1 - e-t/T), where 0.040 m/s and T = 0.50 s. (a) Obtain an expression for a(t). (b) Draw graphs for v(t) and a(t) for the time interval 0 to 2.0 s. (c) Obtain an expression for x(t), choosing the positive x axis as downward, and draw the graph for this func- tion. (d) Use your x(t) graph to determine the time interval needed for the sphere to reach the bottom of the container if the surface of the honey is 0.10 m above the bottom of the jar. ... =

A 2.2×104 kg rocket has a rocket motor that generates 2.7×105 N of thrust. Part A What is the rocket's initial upward acceleration? Express your answer with the appropriate units. Part B At an altitude of 5000 m the rocket's acceleration has increased to 7.5 m/s². What mass of fuel has it burned? Express your answer with the appropriate units.

Please use at least 4 significant figures throughout the entire problem! Also use 9.80m/s2 for the acceleration due to gravity. DO NOT USE 10 M/S2 FOR THE ACCELERATION DUE TO GRAVITY! Thank You.
