Sunee is competing in 5 km (5000m) race. She runs 4902 m at a B velocity of 4.3m/s when sees the finish line. She increases her pace and accelerates at a constant rate until she crosses the finish line 19.4s later. What is her acceleration rate when saw the finish line?

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) determine the magnitude and direction of projectile velocity at t= 1.3s b) determine the magnitude and direction of projectile acceleration at t=1.3s
