PHYS-1110

1. (15pts) Find the magnitude and direction of the resultant R.

R= 4A3B+ 7C.

A= 286 meters at 152B= 86 yards at 55

C= 422 meters at 241

1. While painting, an artist accidentally knocks a jar of paint off the edge of the table with a horizontal velocity of 2.4m/s. The jar will shatter if it hits the floor with a velocity of more than 5.2m/s.

2a. (10pts) What's the tallest the table can be and still not shatter the jar of paint.

2b. (15pts) Using the height you just found, find the horizontal distance from the edge of the table to the point where the jar lands.

1. At a UNO hockey game, a shirt is launched with an initial velocity of 14.5^m_sat an angle of 70above the horizontal. The shirt goes up into the air before coming back down and being caught by a student seated 8mabove the ice.

3a. (10pts) How long does it take the shirt to reach the student?

3b. (10pts) What is the x-distance traveled by the shirt?

3c. (5pts) What is the straight-line distance from the launcher to the student?

1. A UNO golfer hits a ball out of a sand trap up onto the green at an angle of 68. The ball lands on the green 1.7mhigher and 9.3mhorizontally away. 4a. (15pts) What was the initial speed of the ball?

The grass on the green then causes the ball to slow with a deceleration of 1.25_s^m₂. 4b. (10pts) How far will the ball travel on the green before coming to rest?

1. Find the radial acceleration of:

5a. (5pts) The moon around the earth.

5b. (5pts) The earth around the sun.

Report your answers as an order of magnitude.
