The guitar string wire in item 2 was 1.60 m long with a diameter of 0.20 cm. Approximately what tension force would break it?
a volleyball player serves the ball at 1.5m height and horizontally with 0.3m, what is the time of flight of the ball and its horizontal velocity
Determine the resultant of two vectors using the component method and illustrate. Use separate sheet of paper and scientific calculator.
Given: A= 15 Units, 25 Counterclockwise (+) x-axis
B = 30 Units, 40 Counterclockwise (-) x-axis
Two vectors are given: 7 = 3 + 27, y = 27 - 8j.
a) Draw these vectors in Cartesian coordinate system
b) Represent both of these vectors in magnitude, direction notation.
C) Represent vector 27 + 3ÿ in magnitude, direction notation.
Figure a side shows a box of mass m2 = 1.0 kg on a frictionless plane inclined at angle ©= 30°. It is connected by a cord of negligible mass to a box of mass ml = 3.0 kg on a horizontal frictionless surface. The pulley is frictionless and massless.
If the magnitude of horizontal force is 2.3 N.
what is the tension in the connecting cord?
What is the largest value the magnitude of may have without the cord becoming
slack?
A car moves along an r axis through a distance of 900 m, starting at rest (at r = 0) and
ending at rest (at r=900 m). Through the first ¼ of that distance, its acceleration is +2.25 m/s2. Through
the rest of that distance, its acceleration is -0.750 m/s2. What are:
its travel time through the 900 m and
its maximum speed?
Graph position r versus time 1 for the trip,
Graph velocity y versus time 1 for the trip, and
Graph acceleration a versus time 1 for the trip.
A sailboat tacking against the wind moves as follows: 4.2 km at 33° east of north, 3.6 km at 26° west of north, and 3.8 km at 41° east of north. The entire trip takes 1 h and 25 min. What is the displacement of the sailboat at the end of the trip?
A 1500 g object is being pushed by an applied force and accelerates at 4.08 m/s2. what is the force applied if a frictional force is 62.5 n is acting on opposite direction?
A private helicopter flies 250 km west from city A to city B, then covers 100 km north from city B to city C. How far is it from city A to city C? What direction must the helicopter head to return straitly to city A from city C?
A simple pendulum is found to vibrate 50 times within 200s. When 1.5 m of its
length is reduced to certain length, it vibrates 50 times in 175 s. Find the
original length of the pendulum.
