Problem 4: A toy car is rolling down the ramp as shown in the figure. The car's mass is m = 1.1 kg and the ramp makes an angle of 0 = 14 degrees with respect to the horizontal. Assume the car is rolling without friction.
Vector A can be expressed in (i,j,k) notation as 5.0i - 4.0j, and vector B as -7.0i + 2.0j. Determine the value of 3A + 2B in terms of magnitude and angle. The angle can be specified either as a value between 0 and 360 degrees counter- clockwise with respect to the positive x-axis, or as a value between 0 and 90 degrees in the appropriate Cartesian quadrant.

A space shuttle is fired and the position of the shuttle is given by r(t)=(2*t*t-5*t)i+ (3*t+1)j+(12*t*t*t)k where t is in seconds, r is in meters and ij,k are the unit vectors of x,y,z directions respectively. Find the average acceleration of the space shuttle between the time interval t=10 s and t=1 minutes. *
A dog initially at rest, starts running inside a circular track with a 40π m circumference. The dog's acceleration tangent to its path is defined by the function at = 0.1t2 + 0.4t. What is the total distance ran by the dog after t = 10 s?
Myla participated in a running competition. She ran around a circular track with a radius of 1.0 x 102 m. Myla completed the track after 2 minutes. If she had a constant speed, what was Myla’s average speed in the entire run? answer in "m·s", please.
I am having trouble with a 3d motion problem. The problem is as follosw, "At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of i = (3.00 i - 2.00 j) m/s and is at the origin. At t = 2.00 s, the particle's velocity is = (7.00 i + 8.20 j) m/s. (Use the following as necessary: t. Round your coefficients to two decimal places.)" The problem asks me to find acceleration of the particle at any time t and to find its coordinates at any time t. Thanks for the help
