Question

A body of mass 1 kg is thrown with a velocity of 10 m s^–1at an angle of 60° with the horizontal. Its momentum at the highest point is-

• A. 2 kg m s^–1
• B. 3 kg m s^–1
• C. 4 kg m s^–1
• D. 5 kg m s^–1

Answer 1

Answer: (D)

5 kg m s^–1

Answer 2

p cos q = 1 × 10 × cos 60⁰ = 5 kg ms^–1
