By what fraction does your mass increase when you and your car travel down the highway at 70 mph? Assume that the total mass of your car and occupant is 2000 kg.
An air-track glider attached to a spring oscillates between the 10.0 {rm cm} mark and the 58.0 {rm cm} mark on the track. The glider completes 15.0 oscillations in 35.0 {rm s}. What are the (a) period, (b) frequency, (c) amplitude, and (d) highest..
A projectile is shot from the edge of a cliff 140 m above ground level with an initial speed of 100 m/s at an angle of 37 degrees with the horizontal. Find out the time taken by the projectile to hit point at ground level.
At rest, a car's horn sounds at a frequency of 385 Hz. The horn is sounded while the car is moving down the street. A bicyclist moving in the similar direction with one-third the car's speed hears a frequency of 342 Hz. What is the speed of the ca..
