1. A 1.5-kg cart is pulled with a force of 7.3 N at an angle of 40° above the
horizontal. If a kinetic friction force of 3.2 N acts against the motion, the
cart's acceleration along the horizontal surface will be

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.
