a jet propelled motorcycle start from rest moves in a straightline with constant acceleration and covers a distance of 64m in 4seconds.?
yes, it does.
What’s the potential energy of a ball attached to a spring that is stretched 0.2m from its original unstretched position. (Spring constant k=200 N/m)
To find the acceleration of the jet propelled motorcycle, we can use the equation:
distance = initial velocity * time + (1/2) * acceleration * time^2
We are given that the motorcycle starts from rest, so the initial velocity is 0 m/s. The distance covered is 64 m, and the time taken is 4 seconds. Plugging these values into the equation, we get:
64 = 0 * 4 + (1/2) * acceleration * (4^2)
Simplifying the equation, we have:
64 = 0 + 2 * acceleration * 16
Dividing both sides of the equation by 32, we get:
2 = acceleration
Therefore, the acceleration of the jet propelled motorcycle is 2 m/s^2.
