Question 9
A 13 kg object undergoes an acceleration given by a (4 î- 3) m/s?.
The magnitude of the resultant force acting on the object equals:
26, 20-
150 m
Problem (4) A motorcycle is traveling 80 mph (miles per
hour) at point A. Knowing that the motorcycle's speed
decreases at a rate of a, = -(0.04 s) m/s² while traveling
up a 150-meter radius hill from point A (sA = 0) to point
B, determine the traction force of the motorcycle and the
normal reaction the ground imparts on the motorcycle at
point B. The combined mass of the motorcycle and driver
is 340 kilograms.

A dog and a sledge are on the frictionless ice of a frozen lake, 16.3 m
apart but connected by a rope of negligible mass. The dog exerts a certain
horizontal force (N) on the rope. If magnitudes of the sledge and the dog
accelerations are 0.3 m/s? and 0.1 m/s?, respectively. How far from the
dog's initial position (m) do they meet?

- 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.arrow_forwardDescribe a situation in which the net external force on a system is not zero, yet its speed remains constant.arrow_forwardProfessional Application During a visit to the International Space Station, an astronaut was positioned motionless in the center of the station, out of reach of any solid object on which he could exert a force.

- Review. A magician pulls a tablecloth from under a 200-g mug located 30.0 cm from the edge of the cloth. The cloth exerts a friction force of 0.100 N on the mug, and the cloth is pulled with a constant acceleration of 3.00 m/s2. How far does the mug move relative to the horizontal tabletop before the cloth is completely out from under it? Note that the cloth must move more than 30 cm relative to the tabletop during the process.arrow_forwardA magician pulls a tablecloth from under a 200-g mug located 30.0 cm from the edge of the cloth.

- An airplane of mass 1.50 104 kg is in level flight, initially moving at 60.0 m/s. The resistive force exerted by air on the airplane has a magnitude of 4.0 104 N. By Newtons third law, if the engines exert a force on the exhaust gases to expel them out of the back of the engine, the exhaust gases exert a force on the engines in the direction of the airplanes travel. This force is called thrust, and the value of the thrust in this situation is 7.50 104 N.
