.A car starts 200 m west of the town square and moves with a constant velocity of 15 m/s toward the cast. Draw a graph that represents the motion of the car a. Where will the car be 10 minutes later? b. When will the car reach the town square? 5. At the same time the car in #4 left, a truck was 400 m east of the town square moving west at a constant velocity of 12 m/s. Add...

I need help with this problem. "A farm truck moves due east with constant velocity of 9.50 m/s on a limitless, horizontal stretch of road. A boy riding on the back of the truck throws a can of soda upward and catches the projacectile at the same location on the truck bed, but 16.0 m farther down the road. (a) In the frame of reference of the truck, at what angle to the vertical does the boy throw the can?...

A car accelerates from rest at S m/s for 5 seconds. It moves with a constant velocity for 15 seconds, and then decelerates at 5 m/s to come to rest in 5 seconds. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion AND determine the total distance the car travelled. (10 pts.) 4.

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...

If the boat moves at a constant velocity of 8 m/s 30° north of east (this means 30° above the + x axis), what is the boats velocity east and what is the boats velocity east? Would I solve this by doing 8 cos(30) and 8 sin(30)? Can you please let me know? Thanks

Relative Velocity and Projectile Motion . a)An airplane moves horizontally with a constant velocity VA/G 300m/s with respect to ground at height H = 600m. The plane fires a container, which has a speed VC/A = 300m/s and direction α = 300 with respect to the airplane immediately after the firing. The container performs a projectile motion and hits the ground at a horizontal distance L from the point of the firing (see figure a)What is the velocity (horizontal and...

Jason ("J"), parked by the side of an east-west road, is watching a car driven by Priscilla ("P"), which is moving in a westerly direction. Selene ("S"), driving east at a speed of 15 m/s relative to Jason, watches the same car. Take the easterly direction as positive. a) If Jason measures a speed of 20 m/s for car P, what velocity will Selene measure? b) If Jason sees Priscilla brake to a halt in 10s, what acceleration (assumed constant)...
