1.On her trip from home to school, Karla drives along three streets after exiting the driveway. She drives 1.85 miles east, 2.43 miles northeast at an angle of 20 degree and 0.15 miles north[90 degrees with respect to x-axis]. Determine the magnitude of Karla's resultant displacement.

Solve the following problems:

2.(a) A plane is traveling northeast at 30 degrees at 200 km/hr. What is (a) the northward component of its velocity, and (b) the eastward component of its velocity?

(b) If the airplane climbs at an 8-degree angle NW direction with a speed of 60 miles/hr, what are the vertical and horizontal components of its velocity?

3.(a)A speedboat increases its speed uniformly from 20 m/s to 30 m/s in 1 minute. Find the magnitude of its acceleration in m/s2

(b)A race car which was speeding at 45meter/second slows down to 10 meter/second in 40 second. Find the magnitude of its acceleration in m/s2

4 a. A stone dropped down from a bridge 50.0 m high. How long will it take for the stone to hit the water below?

b. A book was dropped down from a building and it reached the ground in 15 s. What is the height of the building?
