What is the acceleration of a car moving at a constant velocity of 30m s in a straight line? A car is moving at a constant speed of 30 m/s in a straight line. The acceleration of the car is zero. What will be the momentum of a car having mass of 1000 kg is […]

Is momentum conserved in all collisions? Momentum is conserved in all collisions but kinetic energy is conserved in elastic collisions only. What is the law of conservation of momentum? The law of conservation of momentum states that in an isolated system the total momentum of two or more bodies acting upon each other remains constant

What is a bullet of mass 10g moving with a velocity of 400m s or a cricket ball? Solution: A bullet of mass 10 g moving with the velocity of 400 m/s and a cricket ball of mass 400 g thrown with the speed of 90 km/h . Then the cricket ball has higher momentum.

What is a bullet of 10 grams moving with a velocity of 400 meters per second? A bullet of mass 10 g moving horizontally with a velocity of 400 m/s strikes a wooden block of mass 2 kg which is suspended by a light inextensible string of length 5 m. As a result, the centre

What is the average velocity of a puck? Puck velocity, blade velocity, ice contact time and distance to the puck were analysed for ten consecutive shots for each technique, for two professional ice hockey players. The total mean puck velocity was 38.0 ± 2.7 m/s vs. 36.4 ± 1.0 m/s. Does a hockey puck need

Does a hockey puck need a force to keep it sliding? A hockey puck sliding across the ice will continue to slide forever if there is no friction, but it does have external forces acting on it (gravity and the normal force, in this case). But these forces balance out, so there is no net

Is a force of 98 N required to just start moving a body of mass? μ = F R = F m g = 98 100 × 9.8 = 1 10 = 0.1. A force of 98N is just able to move a body weighing 45kgf on rough horizontal surface. Is friction opposite to the

How much work is required to accelerate a 1000 kg car from 20m * S 1 to 30m * S 1? The work required to accelerate a 1000 kg car from 20 m/s to 30 m/s is equal to 250,000 joules. Is a 1000 kg vehicle moving with a speed of 20 m per second

What is the average braking force of a 1000 kg car? Answer: The average braking force is 2000 N. How long will it take a force of 10 Newton to stop a mass of 2.5 kg which is moving at 20 m per second? However, negative time is not physically meaningful. Therefore, the magnitude of

What is the mass 1000 kg with velocity 10 meters per second? P = m×v =1000×10=10000kgm/sec. Was this answer helpful? What is the average braking force of a 1000 kg car moving at 10 m s braking to a stop in 5s? Answer: The average braking force is 2000 N. Which has more momentum a
