Given, Mass of a vehicle is m = 1500 kg, a = 1.7 ms–2 (negative acceleration so value of a is negative), we calculate force using formula,
F = m × a = 1500 × –1.7 = –2550 N
Hence, the force between the vehicle and a road, when vehicle is to be stopped is –2550 N.
Given,
Mass of a vehicle is m = 1500 kg, a = 1.7 ms–2
Forumla to find force us F = m × a = 1500 × –1.7 = –2550 N
