Answer:
162.24 m/s
Explanation:
The kinetic energy of the car is given as:
KE = ½ * m * v²
Where m = mass of car
v = velocity of car
= ½ * 1650 * 38.1²
= 1197578.3 J
For the bicycle to have the same KE, then:
1197578.3 = ½ * M * V²
Where M = Mass of bicycle
V = velocity of bicycle
1197578.3 = ½ * 91 * V²
V² = 1197578.3/(91 * ½)
V² = 26320.4
V = 162.24 m/s
The bicycle will have to move at 162.24 m/s to have the same Kinetic energy as the car.
