How far, in meters, will a car travel in 20 seconds at an average speed of 20 m/s?

400 seconds

Step-by-step explanation:

To find the distance, you have to multiply. Since each second=20 meters, you have to multiply 20 x 20 because there are 20 seconds.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
