A 25 Mg sled slides from rest down a 500.0 m slope ( = 0.10) at 37 o from horizontal that ends 2.45 km above the ground. Calculate: t, & v f on the slope, and d H, t air, and the maximum v V in air:
A 250 Mg sled accelerates at 3.0 m/s 2 up a 250 m ramp ( = 0.25) at 53 o from horizontal. Calculate: F a, t ramp, v f ramp, t air, d v, & d H
A 0.10 Mg cycle is accelerated with a force of 500.0 N for 10.0 s before hitting a 25 m ramp at 37 o from horizontal. Draw the system and Calculate: v at bottom & top of ramp, and t, d v, & d H in the air
An airplane is flying horizontally due west at 360 km/hr at an altitude of 0.49 km & drops a 2000 lb bomb. Draw the system and Calculate: t air, maximum v V, & d H.
A 50.0 kg person skis ( = 0.010) down a 3.0 km ski trail with an average slope of 30 o. Draw the system and Calculate: a, t, maximum v on the trail
British Ships had cannons with muzzle velocities of 400 m/s while the cannons at Ft McHenry could fire at 500 m/s. The British could elevate to 45 o while the Americans could elevate to 18 o. Which cannons had the greater range.
Expanding gases produce about 10,000 N of force in a gun barrel. One nation wants to build a cannon that will deliver a 2,000 kg cannon ball 200 km. Calculate the length that the barrel must be. Because you are estimating round g to –10 m/s 2.
