Q. The flywheel has mass 370 with a radius of 0.50 and can rotate up to 530. Assuming all of this stored kinetic energy could be transferred to the linear velocity of the 3200- car, find out the maximum attainable speed of the car.
Q. Two objects attract each other gravitationally with a force of 2.5×10-10 while they are 0.60 apart. Their total mass is 5.0. Find out their individual masses.
A bullet is fired vertically into a 1.3kg block of wood at rest directly above it. If the bullet has a mass of 29g and a speed of 470m/s, how high will the block rise after bullet becomes embedded in it.
An 8.30 kg stone at rest on a spring. The spring is compressed 11 cm by the stone. The stone is after that pushed down an additional 26.00 cm and free. To what highest height (in cm) does the stone rise from that position.
The temperature of the surface of a certain star is 7500K. Most hydrogen atoms at the surface of star are in the electronic ground state. What is the approximate fraction of hydrogen atoms that are in the first excited state (and therefore could e..
Find the total work done on the car
A speedboat starts from rest and accelerates at +2.01 m/s2 for 6.95 s. At the end of this time, the boat continues for the additional 5.70 s with an acceleration of +0.518 m/s2. Following this, the boat accelerates at -1.49 m/s2 for 8.20 s.
A horizontal vinyl record of mass 0.10kg and radius 0.10 m rotates freely about a vertical axis through its center with a rotational speed of 5.10 rad/s.
A projectile is shot from the edge of a cliff 115m above ground level with initial speed of 65m/s at an angle of 35 degrees with the horizontal.
