A stone of 1 kg is thrown with a velocity of 20 m s–1 across the frozen surface of a lake and comes to rest after travelling a distance of 50 m. What is the force of friction between the stone and the ice?
Detailed Solution for Test: Force - Question 6
Here, m = 1kg, u = 20 ms-1, v = 0, s = 50m, F = ?
From v2 - u2 = 2as
0 - (20)2 = 2a x 50 = 100a
a = -400/100
a = -4 ms-2
∴ F = ma
F = 1 (-4)
F = -4 N
