7) A body of mass m, rests on a smooth inclined plane and is attached by a light string over a frictionless pulley to a mass
m, as shown in the diagram.
a) Reproduce the diagram in your answer book and label
the forces acting on the mass m.
b) If mass m, = 25.0 kg and m2 = 6.0 kg, calculate the
tension in the string.

Luke and carrie are driving down a straight section of the interstate at 70 mph in luke's new convertible. carrie is drinking a soda in the passenger seat. when she is done she tosses the bottle straight up in the air, just above the height of the car. what will happen to the bottle if air resistance is neglected? a. the bottle will land in carrie's lap. b. not enough information is given. c. the bottle will land on the interstate in front of the car. d. the bottle will land on the interstate behind the car.

Aball is thrown straight up into the air with a speed of 21 m/s. if the ball has a mass of 0.1 kg, how high does the ball go? acceleration due to gravity is g = 9.8 m/s^2. a. 22.5 m b. 20.0 m c. 25.0 m d. 17.5 m

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called
