A particle is moving in three dimensions and its position vector is given by; 7(t) = (1.9t² + 2.1t) î + (1.2t – 3.4)ĵ + (4.9t³ + 1.1t)k where r is in meters and t is in seconds. Determine the magnitude of the instantaneous acceleration at t = 2s. Express your answer in units of m/s? using one decimal place.

v sin 20 gives the distance x travelled (in feet) by a projectile launched from 32 The formula r% = the ground, with initial velocity v (in feet/sec) and initial angle 0 (in radians or degrees). a. Write an expression for the total differential in x. b. Use the total differential to estimate the error in calculating the range of a projectile with initial velocityv 100 ft/sec and initial angle 0= 50 degrees, with measurement errors of dv = t10 ft/sec (for velocity) and d6==5 degrees (for the initial angle). (Note: remember to use radians for the differential in 0.)

You take a three-day hiking. On the first day, you travel 5.0 km heading East. On the second day you’ve enjoyed the scenery so much that you forgot to take note how far you have walked and in what direction. On the third day, after wandering for 8.5 km and in the direction 37o South of West, you find yourself in the base camp where you have started (which means the total displacement is zero). Determine your displacement during the second day of your trip.
