Using the Mental Math Technique—Compatible Fractions, solve the  following problem:     7  1/10 + 2  1/5. 

Read your test questions carefully.  Many questions will give examples to show you how to write your answer.  When your answer has a fraction, use the / to separate the numerator and denominator.  If your answer has a whole number and a fraction, place a space between the whole number and fraction. Examples:  Three fourths is written as 3/4.                    Five and one half is written as 5 1/2   (not 51/2)   Using the Mental Math Technique—Taking Parts from Wholes, solve the following problem:     9 − 2/9.

Which of the following is true about nitrates and calcium channel blockers?

  A 349 kg car moving at 14.2 m/s hits from behind another car moving at 9.40 m/s in the same direction. If the second car has a mass of 719 kg and a new speed of 11.5 m/s, what is the velocity of the first car after the collision?  

Crests of an ocean wave pass a pier every 13 s. The wave is moving with 2.0 m/s. How far are the crests apart?

A uniform, solid flywheel () of radius 1.4 m and mass 15 kg has an angular momentum of 60.0 . What is the magnitude of  its angular velocity ?

Suppose a train sounding its horn is moving at 30.0 m/s in still air on a day when the speed of sound is 350.0 m/s. As the train passes the platform, on which you stand (moving away from you), you hear it with a frequency of 180 Hz. Which frequency does an observer on the train hear?

A mass m = 7.0 kg is attached to a spring and allowed to hang in the Earth’s gravitational field. The spring stretches 4.4 cm before it reaches its equilibrium position (where the spring force balances gravity). If allowed to oscillate, what would be its period?

A soccer player kicks a 0.500kg ball from rest towards the opposing team’s net. The ball has a velocity of 25.0 m/s the instant after being kicked, and the player’s foot is in contact with the ball for 0.300 s. What is the average force exerted on the ball?

A soccer player kicks a 0.500kg ball from rest towards the opposing team’s net. The ball has a velocity of 24.0 m/s the instant after being kicked, and the player’s foot is in contact with the ball for 0.310 s. What is the average force exerted on the ball?
