Suppose the time between the apparatus leaving your hand and landing on the ground was measured to be t = 4.80 s. What was the velocity of the apparatus leaving your hand?

A woman starts from her home at 9.00 am, walks with a speed of 7 km h-1 on a straight road up to her office 3.5 km away, stays at the office up to 5.00 pm, and returns home by an auto with a speed of 30 km h-1. Choose suitable scales and plot the x-t graph of her motion.

train is travelling with a velocity of 90 km/h. The brakes are applied at a rate of -0.4 m/s2. Calculate the velocity after 8 seconds, the time taken to stop and the distance travelled by the train during the braking period. (i) The velocity of the train 8 s after the brakes are applied is Answer m/s (ii) The time taken to stop the train is Answer s (iii) The distance travelled by the train during the braking period is Answer m

A car travels a distance d=5.4 km during a time interval t=10 minutes. The average speed of this car is

A runner with a good awareness of her pace runs along a path of unknown length at a speed of 0.1250.125 mi/min and then walks back to her starting point at a speed of 0.04500.0450 mi/min. She neglects to note her time for each part of her path but does measure the total round-trip time to be 50.050.0 min. How far did she run? (Do not include walking distance.)

High-speed motion pictures (3500 frames/second) of a jumping 230 μg flea yielded the data to plot the flea's acceleration as a function of time as shown in the figure ( Figure 1). (See "The Flying Leap of the Flea," by M. Rothschild et al. in the November 1973 Scientific American.) This flea was about 2 mm long and jumped at a nearly vertical takeoff angle. Use the measurements shown on the graph to answer the questions. Figure alg 150 100 50 0 0 0.5 1.0 1.5 Part E Use the graph to find the flea's maximum speed.

The velocity V of a small vèhicle was measured, starting from rest. t (s): 0.0 2.5 5.0 7.5 10 V 0.00 0.87 2.49 5.52 11.18 (m/s): What is a reasonable estimate of the acceleration of the vehicle at t = 6.7 s?

We are given the following data about the speed of a vehicle with time: 0 Time (1) Speed (v) 5.2 5 4.8 10 8.3 15 6.0 Compute the value of acceleration (rate of change of velocity) at time t=10 using the forward-difference method. Report your answer correctly to two decimal places (with an appropriate + or - sign).

A car is initially traveling at a rate of 65 feet per second. The acceleration of the car is 3 feet per second squared. Determine the displacement of the car at time t if the displacement at t=5 seconds is 29 feet. Do not include "s(t)=" in your answer.

Two cars leave from the same place at the same time and travel in opposite direction. One car travels at 55 mph and the other at 75 mph. After how many hours will there be 520 miles apart?  Please include the FBD
