Question

Part A A car of mass 899 kg collides head-on with a parked truck of mass 2000 kg. Spring mounted bumpers ensure that the collision is essentially elastic. If the velocity of the truck is 17 km/h (in the same direction as the car's initial velocity) after the collision, what was the initial speed of the car? 54 km/h 41 km/h 27 km/h 14 km/h Submit Request Answer

Step 1

$m_c = 899 kg$ $m_t = 2000 kg$ Let $v_{c,i}$ be the initial velocity of the car and $v_{t,i}$ be the initial velocity of the truck. $v_{t,i} = 0$ (since the truck is parked) Let $v_{c,f}$ be the final velocity of the car and $v_{t,f}$ be the final velocity of the Show more…
