The car rolls from rest down the incline and has a velocity 5 when it reaches the edge of the cliff. The cliff is 35.7 m above the ocean. How far is the car from the base of the cliff when the car hits the ocean? The acceleration of gravity is 9.8 m/s2 Answer in units of m. 002 (part 1 of 2) 10.0 points A particle at rest undergoes an acceleration of 2.5 m/s to the right and 3.9 m/s up What is its speed after 7.8 s? Answer in units of m/s. 003 (part 2 of 2) 10.0 points What is its direction with respect to the hor. izontal at this time? Answer between -180° and 180°. Answer in units of 004 (part 1 of 3) 10.0 points A particle moves in the zy plane with constant acceleration, At time zero, the particle is at 7 m, y 4.5 m and has velocity io (7.5 m/s) i (-6,5 m/s) j. he acceleration is given by m/s i+ (1.5 after What is the z component of velocity 8 s?

Explanation / Answer

002)

given that ax = 2.5 m/s^2

ay = 3.9 m/s^2

a = sqrt(ax^2+ay^2) = sqrt(2.5^2+3.9^2) = 4.63 m/sec

time taken is t = 7.8 sec

Using kinematic equation

V = Vo+(a*t)

Vo is the initial velocity = 0 m/sec

V = 0 + (4.63*7.8) = 36.12 m/sec

003)

theta = tan^(-1)(3.9/2.5) = 57.33 degrees above the horizontal
