(a)What are the horizontal and vertical components of the ball’s initial velocity?
(b)Find the maximum height above the ball can reach.
(c) What are the horizontal and vertical components of the ball’s velocity and acceleration at its maximum height?
Two particles, A and B, are moving in a straight line. Take this to be the x-axis. At t = 0, particle A is trailing particle B, initially at some distance x behind B. Particle B is accelerating at a constant 2.00 m/s2 and particle A is constantly accelerating at 3.00 m/s2. Particle A was able to overtake B after B has moved 50.0 m
(a)How long does it take for particle A to overtake B?
(b)Initially, how far was A behind B?
(c)How fast are the two particles moving as soon as they’re at the same position?
What is the horizontal distance from the base of the cliff where the stone lands.
*hint* you will have to solve for time in the cortical direction friest before you can solve for the answer.
Answer in units of J.
A jogger (of mass 60 kg) has the same kinetic
energy as that of the continent.
What would his speed be?
Answer in units of m/s.
16 m with locked brakes.
How far will the car skid with locked brakes
at 86 km/h? Assume that energy loss is due
only to sliding friction.
Answer in units of m
A mass of gas at an initial internal energy of 300 kJ is allowed to expand behind a piston untill it's internal energy is 200 kJ, the value of final pressure and volume are 4.59 bar and 0.148 m^3 respectively, the law of expansion is PV^2 =C calculate
1) work done
2) initial volume.
