76. A ball is projected at 20 m/s at 30^circ (g = 9.8 m/s^2). Its horizontal range is:

  1. 35.3 m
  2. 40.8 m
  3. 17.7 m
  4. 70.7 m

Answer: A) 35.3 m

Explanation: R = u^2sin 2thetag = 35.3 m. SLO P-11-B-05 · Application

77. A body's velocity changes from 30 m/s to 0 m/s over 90 m. Its acceleration is:

  1. -10 m/s^2
  2. 5 m/s^2
  3. -5 m/s^2
  4. -2.5 m/s^2

Answer: C) -5 m/s^2

Explanation: a = v^2 - u^22s = 0 - 9002(90) = -5 m/s^2. SLO P-11-B-04 · Application

78. A car starts with velocity 0 m/s and accelerates at 4 m/s^2 for 3 s. Its final velocity is:

  1. 6 m/s
  2. 12 m/s
  3. 18 m/s
  4. 24 m/s

Answer: B) 12 m/s

Explanation: v = u + at = 0 + (4)(3) = 12 m/s. SLO P-11-B-04 · Application

79. A ball is projected at 30 m/s at 45^circ (g = 9.8 m/s^2). Its maximum height is:

  1. 23 m
  2. 45.9 m
  3. 11.5 m
  4. 24 m

Answer: A) 23 m

Explanation: H = u^2sin^2theta2g = 23 m. SLO P-11-B-05 · Application
