(for problems 1 - 3) the velocity v (in cm/s) of a rolling ball at time t (in seconds) is recorded below. t 0 1 2 3 4 5 6 7 8 v 1.0 2.0 4.0 8.0 16.0 32.0 64.0 128.0 256.0 estimate the total distance the ball traveled during the eight-second interval by finding: 1. r4 = 2. m4 = 3. l4 =

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

Acharge of 8.4x10^-4 c moves at an angle of 35 degrees to a magnetic field that has a field strength of 6.7x10^-3 t. if the magnetic force is 3.5 x10 ^-2 n, how fast is the charge moving?
