PROBLEM SOLVING.

In a festival with fireworks display, a shell is to be shot into the air using a fuse that is timed to ignite the shell just as it reaches its highest point above the ground. If the shell has an initial speed of 60.0 m/s at an angle of 70.0' above the horizontal, b) what is the height of the shell when it explodes; c) what is the horizontal displacement of the shell when it explodes; 162 m, 91.8 m 171 m, 91.8 m 162 m, 118 m 171 m, 118 mIn a festival with fireworks display, a shell is to be shot into the air using a fuse that is timed to ignite the shell just as it reaches its highest point above the ground.

If the shell has an initial speed of 60.0 m/s at an angle of 70.0' above the horizontal, a) how much time passes between the launch and the explosion? C 5.75 s 5.91 s 5.57 s C 5.19 sYou drive north on a straight two-lane road at a constant 65 km/h. A truck in the other lane approaches you at a constant 166 km/h. What is the truck's velocity relative to you? O -104 km/h O -231 km/h C -101 km/h O -234 km/hA satellite is in circular polar orbit around Earth at an altitude of 450 km - meaning it passes directly overhead of the North and South Poles. What is the magnitude and direction of the displacement vector when it is directly over the North Pole to when it is at 40' latitude? Earth's radius is 6,370 km. O 12,362 km, 25" O 5,764 km, 25* 5,764 km, 65 O 12,362 km, 65"A jet is flying at 132.4 m/s along a straight line and makes a turn along a circular path level with the ground. What does the radius of the circle have to be to produce a centripetal acceleration of 1.78 g on the pilot and jet toward the center of the circular trajectory? g is acceleration due to gravity 8.701 km 10.02 km 9.848 km O 8.554 km
