All angles are measured as anti-clockwise rotations from the +x-axis. An object has an initial velocity of 2.91 m/s at 26.6 degrees. 6.6 seconds later it is moving at 91.15 m/s at an angle of 131.5 degrees. What acceleration caused this change in velocity? (Give your answer in terms of the +x-axis, in degrees)
Acceleration =
,
Angle =
from the positive x axis.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

If an astronaut takes an object to the moon the following is true (choose only one). a the mass will change but the weight will be the same. b both the mass and the weight of the object will be the same. c the weight will change but the mass will be the same. d both the mass and the weight of the object will change.
