Atelevision camera at ground level is filming at the lift-off of a space shuttle that is rising vertically according to the position equation s = 50t 2, where s is measured in feet and t is measured in seconds. the camera is 2000 ft from the launch pad. what is the rate of change in the angle of elevation of the camera 10 seconds after lift-off?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

Arrange the images in order to show how lake-effect snow occurs.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
