After a ball rolls off the edge of a horizontal table at time t = 0, its velocity as a function of time is given by v=1.2i9.8tj where v is in meters per second and t is in seconds. The balls displacement away from the edge of the table, during the time interval of 0.380 s for which the ball is in flight, is given by r=00.3803vdt To perform the integral, you can use the calculus theorem [A+Bf(x)]dx=Adx+Bf(x)dx You can think of the units and unit vectors as constants, represented by A and B. Perform the integration to calculate the displacement of the ball from the edge of the table at 0.380 s.
Scalars and Vectors A weather forecast states the temperature is predicted to be 5Cthe following day. Is this temperature a vector or a scalar quantity? Explain.
The Moon is about 3.8 x 10° m from Earth. Traveling at the speed of light, 3.0 x 10° m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)? The same physics was responsible for the noticeable delay in communications signals between lunar astronauts and controllers at the Houston Space Flight Center. S

50 40- 30 20 10- -10 10 20 30 10 You are a lifeguard and spot a drowning child 30 meters along the shore and 50 meters from the shore to the child. You run along the shore for a while and then jump into the water and swim from there directly to child. You can run at a rate of 3 meters per second and swim at a rate of 1.2 meters per second. How far along the shore should you run before jumping into the water in order to save the child? Round your answer to the hundredths decimal places.
Conversations with astronauts on the lunar surface were characterized by a kind of echo in which the earthbound person's voice was so loud in the astronaut's space helmet that it was picked up by the astronaut's microphone and transmitted back to Earth. It is reasonable to assume that the echo time equals the time necessary for the radio wave to travel from the Earth to the Moon and back (that is, neglecting any time delays in the electronic equipment). Calculate the distance from Earth to the Moon given that the echo time was 2.56 s and that radio waves travel at the speed of light (3.00×108 m/s) .
