Calculate the normal force on a 15.0 kg block in the following circumstances: (a) The block is resting on a level surface. (b) The block is resting on a surface tilted up at a 30.0 angle with respect to the horizontal. (c) The block is resting on the floor of an elevator that is accelerating upwards at 3.00 m./s2. (d) The block is on a level surface and a force of 125 N is exerted on it at an angle of 30.0 above the horizontal. (Sec Section 1.5.)
A box with mass m1 = 6.00 kg sliding on a rough table with a coefficient of kinetic friction of 0.220 is connected by a mass-less cord strung over a mass-less, frictionless pulley to a second box of mass m2 = 12.0 kg hanging from the side of the table (Fig. P5.51). What is the tension in the cord connecting the boxes?
Describe a situation in which the net external force on a system is not zero, yet its speed remains constant.
As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 61.0 kg. If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 6.00 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine (a) the salmons acceleration and (b) the magnitude of the force F during this interval.
A potato of mass 0.5 kg moves under Earth’s gravity with an air resistive force of −kmv. (a) Find the terminal velocity if the potato is released from rest and k = 0.01 s−1. (b) Find the maximum height of the potato if it has the same value of k, but it is initially shot directly upward with a student-made potato gun with an initial velocity of 120 m/s.

--> Newton's third law <-- An apple of mass 0.1 kg falls from a tree to the ground 2.0m below. a) How long does it take the apple to hit the ground? b) During the fall, what magnitude of force does the apple exert on the Earth? c) Taking the Earth mass to be 6 × 1024kg, approximately how far does the Earth move towards the apple during the fall? d) During the fall, is the apple moving, the Earth moving, or both, or neither? Explain the answer for me please! e) In the real world, is the force exerted by the apple on the Earth of exactlythe same magnitude as the force exerted by the Earth on the apple?
A 6.38 × 103-kg lunar landing craft is about to touch down on the surface of the moon, where the acceleration due to gravity is 1.60 m/s2. At an altitude of 264 m the craft's downward velocity is 26.9 m/s. To slow down the craft, a retrorocket is firing to provide an upward thrust. Assuming the descent is vertical, find the magnitude of the thrust needed to reduce the velocity to zero at the instant when the craft touches the lunar surface.
