Tara's cell phone plan costs $39.00 a month, which includes 100 text messages. After she uses all of her text messages, it will cost her $.15 per text message

A net force of 10.0 N causes an object to accelerate at 20.00 m/s^2. What is the mass of the object?

A rubber ball weighs 49 N ... a) What is the mass of the ball? (Answer: 5.0 kg). b) What is the acceleration of the ball if an upward force of 69 N is applied? (Answer: 4.0 m/s/s). For a) I used the equation W = Fg = mg, which becomes 49 = m (9.8).

On a frictionless air track, cart A hits cart B moving at a velocity of 2 meters per second to the right. Which answer predicts what will happen?

True or False? An airplane is flying West at 200 kilometers per hour 2 hours later it is flying West at 300 km/h its average acceleration is 100 kilometers per hour.

Science investigators initially use classification system to

Describe how velocity and speed are different

The slope of a velocity versus time graph gives
