1.Easy
v = ?h = 65 m

A stone is dropped from rest from a bridge 65 m above the water. Ignore air resistance and use g = 9.81 m/s². Find its speed v just before it hits the water.

v₀ = 0h = 65 mg = 9.81 m/s²
v = m/s
2.Easy
v = ?h = 25 m

A stone is dropped from rest from a bridge 25 m above the water. Ignore air resistance and use g = 9.81 m/s². Find its speed v just before it hits the water.

v₀ = 0h = 25 mg = 9.81 m/s²
v = m/s
3.Medium
t (s)v (m/s)t = ?22.22

A car driving at 80 km/h brakes with a constant deceleration of 8 m/s² until it stops. How long does braking take? Find t.

v₀ = 80 km/ha = −8 m/s²v = 0
t = s
4.Medium
a = 2.25 m/s²s = 1300 m

A plane starts from rest and accelerates uniformly at 2.25 m/s² along a runway. Find its speed v after 1300 m.

v₀ = 0a = 2.25 m/s²s = 1300 m
v = m/s
5.Hard
v₀ = 20 m/s20 m

A ball is thrown straight up at 20 m/s from the edge of a roof 20 m above the ground. Ignore air resistance and use g = 9.81 m/s². How long after the throw does it hit the ground? Find t.

v₀ = 20 m/sh₀ = 20 mg = 9.81 m/s²
t = s
6.Hard
v₀ = 10 m/s5 m

A ball is thrown straight up at 10 m/s from the edge of a roof 5 m above the ground. Ignore air resistance and use g = 9.81 m/s². How long after the throw does it hit the ground? Find t.

v₀ = 10 m/sh₀ = 5 mg = 9.81 m/s²
t = s

Answer key

  1. 1. v = 35.71 m/s
  2. 2. v = 22.15 m/s
  3. 3. t = 2.778 s
  4. 4. v = 76.49 m/s
  5. 5. t = 4.908 s
  6. 6. t = 2.454 s
