Your motion begins at rest and consists of acceleration at 2.0
Your motion begins at rest and consists of acceleration at 2.0 m/s2 for 10 seconds, then a period of 6.0 seconds with no acceleration, then deceleration at -1.0 m/s2 for 20 seconds, resulting in a final speed of zero. The total distance traveled is 420 m. What is your average speed during this motion?A projectile is launched from ground level at an angle 45Â° above the horizontal. It returns to the ground 100 m from its launch point. What is the maximum height reached by the projectile?I have $11.85 composed of quarters and dimes. The number of dimes is 10 more than the number of quarters. How many quarters do I have?(Note: 1 quarter = $0.25, 1 dime = $0.10)(For screenshot attched)C. Find R = A – B, where A has magnitude 8.0 and polar angle +45Â°, and B has magnitude 9.0 and polar angle +240Â°:E. If A = 2.00 i – 4.00 j and B = -5.00 i + 7.00 j, what is the direction (angle) of the vector sum A + B?
